DIY Nexia power steering repair

In detail: do-it-yourself repair of the Daewoo Nexia power steering from a real master for the site my.housecope.com.

Daewoo Nexia, like every car, must have weak points. One of them is the steering rack. The knock and rumble when driving will not please anyone, especially when it comes to the steering mechanism. The new Nexia steering rack is capable of silently depart no more than 30-40 thousand km, after which the rake starts knocking. Regardless of whether the car is with or without power steering. You should not panic in such cases; instead, you can tighten the steering rack on the Daewoo Nexia, moreover, in two different ways.

With a strong running knock, the rail will only be saved by repair or a complete replacement.

The brace removes the extra clearance between the gear and the rack.

However, if the steering gear is tightened in time, the mileage before the steering overhaul can be increased. For tightening, we need either keys for 26 and 50, or a hammer, a long beard with a bent end and the same key for 26. The first option is for the lazy:

We install the car on a level surface.
We substitute anti-rollbacks under the rear wheels.
We tear off the bolts of the left wheel.
We hang out the left side and remove the wheel.
We turn the steering wheel all the way to the right.
For insurance, we install a stand under the lever.

We hang out the wheel of the car and put the stand.

This is how the adjustment process looks on the removed steering gear.

The second option for tightening the rail is more convenient, but also more time consuming. In this case, for adjustment, we will remove the vacuum brake booster.

With the vacuum brake booster removed, access to the rack is opened from above.

If you remove it, then we can more accurately adjust the gap between the rail and the plunger.
To loosen the castellated lock nut, we will use a spanner wrench of 50, and the rest, in terms of parameters and methodology, the algorithm corresponds to the previous one.
In the latter case, after adjustment, we will be able to tighten the locknut with a nominal force of 70 Nm and at the same time hold the adjusting plug with a 26 key. This will improve the accuracy of the adjustment.

For the convenience of tightening, some craftsmen make such a short key for 50, but the problem is that on old Nexias the locknut is often knocked down and the key turns.

If the steering wheel rotates freely on the move, the backlash is within the permissible 10 degrees and when turning the wheels themselves return to the neutral position, the adjustment was successful. Good luck to everyone, smooth roads and smooth turns!

Automotive steering rack has been used in automobile construction for a long time. Without this detail, transport control becomes impossible. With the development of technical progress, mechanical steering racks began to be replaced by hydraulic and electrical ones. The steering rack, which is part of the Daewoo Nexia mechanism, is used in conjunction with power steering (power steering). Such a mechanism allows to reduce the mechanical costs of the driver's forces while driving.

Every Daewoo Nexia car owner should know how the steering rack structure works.
Important!In the USSR, the power steering was first used in 1950 for the MAZ-525 dump truck.

The rail consists of the following parts:

The power steering pump is directly connected to the engine and is driven by a gear change. A high pressure pump draws hydraulic fluid into the distributor. The valve is part of the crankcase mechanism (housing).

In the stationary mode of the car, no forces act on the Nexia steering rack, while the distributor channels are blocked, the oil remains in the reservoir.If the car is set in motion and turns into turns, that is, turn the steering wheel, there is resistance from the wheels. At the same time, the torsion bar, which is part of the distributor, begins to twist.

During this time, hydraulic fluid is supplied from the distributor to the steering rack. Then the oil falls in the right direction and presses on the rail.

Important! Every 50-60 thousand km of run it is necessary to change the hydraulic fluid in the steering gear system.

This mechanism is almost always in a dynamic state, so it is necessary to regularly monitor the condition of oil seals, bushings, bearings, etc. To do this, you do not need to disassemble half of the car, it is enough to check if oil is flowing from the front of the car.

There can be many signs of a defective steering gear. But most importantly, if you hear a knock from under the front axle, it's time to go to the auto repair shop.

Here are all the signs that a gearbox needs repair:

When turning the car, you have to turn the steering wheel strongly.
At high speed, he begins to throw the steering wheel and skid to the sides.
When driving on uneven terrain, a knock and recoil starts at the steering wheel when it is in its central position, while cornering the recoil disappears.
General breakdown of the hydraulic fluid in the system.
After entering the turn, the wheels of the car return poorly to their original position.
When driving at high speeds, the steering wheel begins to vibrate and rotate spontaneously.
Oil leakage from the power steering system, which indicates damage to oil seals, anthers, Teflon rings, etc.

If at least one of the above points can be attributed to your car, then you need to do an urgent inspection of the car. After all, if you do not prevent damage, the steering rack of your Daewoo Nexia can become completely faulty at high speed, and this entails sad consequences.

The main reason for the deterioration of steering racks in our country is low-quality roads. The service life of your gearbox is directly proportional to the quality of the roads. If you do not slow down in front of the pits or go around them, over time you will feel the characteristic knock of the front axle, which will be the first signal of a malfunction.

Did you know? The steering wheel first appeared in France in 1894.

Winter drift is considered to be another option for gearbox breakage. When the wheels are turned out and at the same time do not rotate, they give a tremendous load on the crankcase and shaft. At the same time, there is a risk of damage to the oil seals and anthers, as a result, dirt begins to get into the system, which over time destroys the entire mechanism. It is also worth remembering to regularly change the hydraulic fluid in the system.

According to statistics, the most frequent repairs of the Daewoo Nexia steering wheel are due to wear on the slide, seals and stem. Often times, bearing crashes are caused by knocking in bearings, which are bumped on a regular basis. An imbalance in the bearings impairs the correct functioning of the gearbox.

Diagnostics of the Nexia Reiki must be carried out in three stages:

Initial inspection of the mechanism's performance on the car.
Diagnostics after removing the mechanism, checking the backlash, integrity of oil seals, bushings and bearings.
Detailed inspection of all components of the steering gear.

At the first stage, we need to make sure which mechanism failed. Are there any breakdowns in the auxiliary mechanisms. Check the integrity of the system and the presence of hydraulic fluid. We also check the backlash on the bushings.

Important! In winter, before driving, you need to turn the steering wheel in different directions several times, so the risk of damage to the steering mechanism is reduced.

At the second stage, the entire mechanism must be clamped in a vice. Next, check the output along the teeth in the worm pair. You should definitely make sure that the apples of the steering rods do not rust. All this is done in order to understand whether a complete replacement of the rail is needed or only a part of its mechanism.

In the third stage, each element of the mechanism is checked separately.After a detailed check, a conclusion is made about possible malfunctions in the mechanism.

If the backlash is not strong, then perhaps the repair of the rail on your Daewoo Nexia will not be needed. The backlash can be eliminated by the first tightening of the gearbox.

But it is worth noting that the backlash does not have to disappear without a trace. The fact is that without opening we cannot find out the degree of wear of gears, torsion teeth, etc.

Did you know? The first power steering patent was issued in Great Britain in 1902. Frederick Lanchester became its rightful owner.

Still, it is worth tightening the rail (you need the help of a friend), and if the tightening does not give the desired result, then you should contact a car service.

To carry out this manipulation, you must adhere to this plan:

The main task is to tighten the adjusting screw, which is located in the end cover of the steering gear.
To carry out this manipulation, you will need a garage pit, and if it is not there, then use a jack.
Before operating the jack, the wheels of the machine must be set in a straight position.
The steering wheel play can be measured with a play meter. The indicator should not exceed 10 ° (this is what GOST says).
The tightening should be done slowly. After scrolling a little, you need to check if the play on the steering wheel has disappeared.
Check the car in dynamics, if at speed you feel heaviness while cornering, you will need to loosen the adjusting screw.

If the backlash and knocking have disappeared, the steering wheel does not vibrate at speed, and you do not have to exert effort when cornering, then the problem is considered solved. Otherwise, you need to contact a car repair shop.

Replacing the Nexia steering rack may only be required after a complete inspection of the mechanism by professionals. In the best case, only repair or replacement of individual parts of the mechanism may be required.

Important! Using power steering at high speeds requires minimal effort to turn the steering wheel, and at low speeds, more effort is required.

Repair of the steering rack in the workshop is done in this way:

Did you know? Telescopic steering wheel adjustment first appeared on Ford cars in 1955.

All of the above steps for replacing the Nexia rail should be carried out only with experience and special equipment. Otherwise, it is better to go to a workshop.

The new Nexia steering rack with power steering has a decent price, so motorists recommend following some tips to avoid damage to the mechanism.

Helpful hints:

Monitor the condition of the anthers and oil seals. Damaging them is the first step to breaking the entire mechanism.
When twisting the steering wheel to its extreme position, do not leave it there for more than 5 seconds. Do not run the engine at high revs while cranking the steering wheel fully. This leads to wear of the power steering, steering gear, etc.
It is worth abandoning the winter "drift" if you do not want to constantly go to the auto repair shop.
In the workshop, try to control the entire process of disassembling and assembling the mechanism. Mechanics often forget to tighten any nuts. In addition, you need to ensure that the work is done with clean hands, as dirt can get into the system, which will lead to problems within a few days after the repair.

If you adhere to these tips, then the longest possible operation of the mechanism without repair will be ensured.

Diagnosis: working out on the worm shaft, although it may be that it should look like this, but it is somehow not great.

IMHO, when tightening, the upper edge of the shaft tooth revels in the depth between the teeth on the rail, as a result, the steering wheel turns hard, and the gap does not disappear anywhere.
T.K. There are no spare parts for the rail in the power steering, then I had only one way out - I slightly grinded off the metal on the tops of the shaft teeth with a grinder (it can sit deeper).

This is how the shaft began to look after processing.

Reassemble in reverse order.

After assembly, the steering wheel is almost upside down, but this is easily corrected by the steering wheel itself.

After the repair, the knocks became noticeably less, I'll try to tighten it up.

Verdict: Perhaps this will help for a while, but this is not an option. I plan to replace my rail, but it is expensive with a power steering, I will install it without a power steering, hence the question, what to do with the pump?
Maybe if you keep the rail in a slightly overtightened state (the grip area of the teeth is larger), then it will last longer, but not a fact, the metal on the shaft is very soft.

After the tightening, I will unsubscribe, I apologize for possible mistakes (too lazy to re-read.)

Over the years, cars have received many additional systems that provide driving comfort. One of them is the power steering, which is now installed not only on expensive cars, but also on some configurations of the budget Daewoo Nexia.

The power steering itself is very convenient, with it the steering wheel turns incredibly easily and even during long trips around the city, your hands do not get tired. But, like any other, moreover, it is quite complex and highly loaded, the mechanism, the hydraulic booster requires periodic maintenance and is subject to a number of possible breakdowns.

Modern power steering consists of a fluid circuit, a reservoir, a pump and a hydraulic unit. It can also use electronic control units that allow you to distribute the load more intelligently, depending on the speed of the car (the slower - the more effort). The hydraulic unit consists of a double-sided cylinder with a piston, it is connected directly to the steering bipod.

With straight motion, the oil in the system constantly circulates in a circle without creating pressure on the piston. But when you turn the steering wheel, the rotary valve also moves, which changes the distribution of oil on both sides of the piston. On the one hand, the pressure is built up, and from the other, the oil is pumped out into the reservoir. The increased hydraulic pressure displaces the piston, which presses against the steering arm and removes some of the force from the steering wheel.

Schematically, the system in Daewoo is relatively simple, but all of its elements operate under high load, which leads to relatively frequent leaks of hydraulic fluid. Also, the pump or its individual elements, for example, a belt, may fail.

Power Steering Hydraulic Pump for Daewoo Nexia

The most common problem with power steering on Daewoo Nexia is oil leakage. Periodically, oil seals rot or wear out in the system, from where oil begins to leak. In fact, almost all power steering systems are subject to a similar problem.

Drivers often do not pay attention to small leaks in a couple of drops of oil. But any small leak will sooner or later develop into a full-fledged leak, and you may be left without hydraulic fluid in the middle of the road, which will lead to damage to the pump and generator.

The Daewoo Nexia has two standard power steering leaks: in the pump area and near the pedals, at the driver's feet. In the case of a pump, you need to accurately find the place of the leak, it can be both the hoses and their connections, and the pump itself, then you will have to disassemble it and change the gaskets. And if a leak is found in the area of the pedal assembly, then you need to buy a set of new oil seals and replace them.

Another popular problem is pump failure. There may be many reasons, but the pump is simple in design, easily disassembled and you can either replace it completely or purchase individual parts.

Belt leading to the power steering pump on Daewoo Nexia

Also, when turning the steering wheel on Daewoo Nexia, noise or whistling may appear. This problem is definitely related to the power steering, but it is not always possible to determine the source of the noise. First of all, you need to check the belt leading to the pump. It could sag, wear out or get dirty in oil, which causes slippage, in which case everything is solved by replacing. If it's not about the belt, then it's worth checking the pump bearing.

The power steering requires certain maintenance, in particular, you need to periodically change the fluid.The difficulty is that the exact mileage figures for Daewoo are not indicated anywhere. Many drivers drive 100 thousand kilometers or more, but this is not recommended, the community of Nexia owners agreed that the fluid needs to be changed every 50 thousand kilometers.

The procedure is relatively simple, you will need a set of simple tools (wrenches, pliers, screwdrivers), a few empty dishes, rags and gasoline. You also need hydraulic fluid or transmission oil for automatic transmissions.

When replacing, you need to raise the front of the Nexia, open the hood and find the power steering fluid reservoir. You can drain the oil from it in two ways - immediately disconnect the pipe and quickly substitute a relatively large vessel so that oil does not flood the entire engine compartment. But motorists recommend buying a rubber bulb at the pharmacy and pumping out the oil from the tank with it, and only then disconnecting the hoses, so there are less risks.

Changing fluid in power steering Daewoo Nexia

After the oil has been drained, the system hoses must be immediately put into a collection container and, with the engine turned off, turn the steering wheel in both directions until it stops, this will help drain the oil from the circuit.

It is best to rinse the removed tank with regular gasoline. It is worth noting that there is a filter inside the Nexia tank, it cannot be removed, but it can be unscrewed and washed inside the tank.

Then you need to return the tank to its place, connect the hoses and fill in new fluid to the maximum mark. After that, you need to turn the steering wheel of your Daewoo from stop to stop again, some of the oil will go away and you will need to add more, and then turn the steering wheel again. If the level has dropped again, top up again to max (the liquid level must be watched with the wheels aligned exactly). But this is not all, after the oil is poured, you need to start the car and turn the steering wheel again from lock to lock and check the level again.

the rake lets you know by the following signs:

the appearance of knocking under the hood;
the presence of oily stains in the parking lot;
the need to constantly add fluid to the power steering tank;
the steering wheel becomes "heavy", sometimes it becomes jammed;
a large backlash appears on the steering wheel.

These and a number of other signs are characterized by malfunctions that have arisen in the steering rack. They also appear when other steering assemblies break down. High-quality diagnostics at a specialized car service will be able to identify the true cause and location of the malfunction.

The quality of the diagnosis depends only on the place where it is carried out. In garage conditions, it is absolutely not feasible. The fact is that to carry it out in full, special equipment is needed - a diagnostic stand.Without it, the whole process of diagnosing the steering rack will be reduced to a simple inspection. The result will be another failure.

Special equipment, fixtures and tools are available in full only at specialized service stations. Qualified diagnosticians will be able to determine the malfunction with great accuracy and help the car owner find the best ways to eliminate it. Depending on the breakdown, it is sometimes enough to replace a small part to restore the rail performance. But there are cases when you have to change the entire assembly assembly.

The decision on the further possibility of operating the rail, and therefore the car, will depend on timely diagnostics. The road traffic regulations clearly define malfunctions, in the presence of which driving is prohibited. Steering in this prohibition takes priority.

The restoration of the steering rack can only be carried out at specialized service stations. Given her direct participation in maintaining traffic safety, there can be no question of any garage repairs. A simple example: you need a lathe to rebuild. It is unlikely that it is in the garage. In addition, for a restored rail (as well as after replacing it with a completely new one), its adjustment is mandatory.

The renovation process consists of

from several operations. It makes no sense to list them all. To understand the complexity of reiki recovery, it is enough to know about the following:

dismantling from the car;
complete disassembly;
thorough fault detection of every detail;
replacement of worn out parts;
assembly;
performance check on a special diagnostic stand;
installation on a car with mandatory diagnostics of the entire mechanism.

In fact, there are more than 20 operations, but a certain conclusion can be drawn from the listed ones.

The process of replacing the rail itself is not

so difficult, but it will cause a lot of unpleasant moments. Especially for those who decide to do it on their own. What troubles lie in wait when replacing the steering rack? Unfortunately, there are quite a few of them. Firstly, it is simply not possible to remove it without a special tool. Secondly, you need to know the sequence of operations during its dismantling and installation. Otherwise, a situation like “and the nut unscrewed, and the bolt jumped out, but the rail would not be removed. Maybe it was welded with electric welding? "

To avoid such situations, there is only one way out: the work must be performed by specialists. Only they are able to determine what exactly needs to be replaced in the rail or to replace it completely.

Replacing the steering rack at a service station will have a beneficial effect on traffic safety, and this guarantee for this work will provide confidence and peace of mind to every motorist.

There are not many reasons for the occurrence of malfunctions. Oddly enough, they all come together under a common name - improper vehicle operation. Mistakes are made by the driver either out of ignorance, or from the hope of "maybe". For example, not everyone knows that the maximum load on the crankcase and

the shaft occurs when the wheels are completely turned out without rotation. It is this moment that most often leads to damage to the oil seals along with the anthers. The access of dirt to the mechanism is provided. Reiki has not long left to "live".

Not driving neatly on bumps, untimely topping up of fluid in the power steering (power steering), as well as using a different brand of fluid for topping up, also does not contribute to the extension of the service life of the rack. If you add to the above the untimely maintenance (maintenance), then the rail will have to be changed very soon.

Daewoo Nexia has a long history. The direct successor of Opel Kadett, this model of the Korean car industry is currently produced in Uzbekistan. Over the entire production period, the model has "grown" by only one generation, but it still remains one of the most demanded in the Russian and CIS markets. Due to the great age of many cars, the issue of repair, and in particular the repair of the Daewoo Nexia power steering, is relevant.

Complete diagnostics of power steering after removal and disassembly.

If we make repairs, then this is included in the cost of work.

Complete diagnostics of the STEERING RACK.

If we make repairs, then this is included in the cost of work.

The specific cause of the breakdown can only be named after a thorough technical inspection of the car. But, as a rule, most of the breakdowns are due to untimely maintenance, poor-quality repair of the Daewoo Nexia power steering, or simply due to the great age of the parts themselves. After all, the model has been produced since 1994.

It is impossible to describe all types of breakdowns, but here are the most relevant ones:

Replacing the power steering fluid. This item is the leader among all brands and models of cars. The situation is aggravated by the fact that in the official Daewoo Nexia manual there is no exact answer when it is worth changing the fluid, which is why some drivers do not make a replacement at all. The results are quite deplorable - an expensive repair of the Daewoo Nexia power steering with a complete replacement of all parts.
Steering rack corrosion. Another known problem for the owners of this car. It manifests itself in a tight turn of the steering wheel, it is often eliminated without replacement, only good cleaning is required.
Leaking in the cistern. The main source of this failure is a worn out gland, or a damaged hose. Both at the service station will be replaced quickly and inexpensively.
Knock when turning the steering wheel. A very popular problem, the solution to which lies in the replacement of bushings and worm gear.

Most minor breakdowns can be repaired on their own, sometimes even without a special tool. But do not forget about regular maintenance, as well as trying to independently repair complex control systems, such as a power steering. Improper repairs will not only take your time, but can also lead to further breakdowns, which will eventually lead you to the service station. service, but you will have to pay a large amount.

If there are any problems in the operation of the power-steering system of your car, please contact our contact numbers, and the managers will provide all the necessary advice.

Hydraulic power steering is used to reduce the amount of effort required to steer the vehicle's wheels, which improves comfort and reduces driver fatigue. The inventor of the power steering is the American Francis Davis, who received a patent for his invention in 1925, and in 1950 the power steering was first installed on a serial Cadillac. The first power steering in the USSR began to be installed on MAZ trucks, after which they appeared on the GAZ-66 and UAZ. Today, hydraulic power steering is installed in almost any passenger car. The development of technology does not stand still: the world famous Mercedes cars are equipped with a hydro-electric amplifier, and Opel has gone even further and installs an all-electric amplifier on its cars.

The photo shows the power steering, which increases driving comfort for the driver.

Power steering is a relatively simple and unpretentious mechanism in operation, which consists of:

a hydraulic pump, the main task of which is to pump oil and create operating pressure in the system
distributor, which is responsible for directing the oil to the desired chamber
torsion bar, which, by twisting in the right direction, supplies fluid to the distributor
a hydraulic cylinder responsible for converting the energy of fluid pressure into the translational movement of the piston. It is this unit that directly pushes special rods, which help the driver to turn the steering wheel.

Like any machine unit, the power steering elements are subject to wear and tear and require both periodic maintenance and repair. The distributor, torsion bar and hydraulic cylinder are quite reliable parts and rarely fail, often amplifier malfunctions occur due to oil leakage as a result of mechanical damage to a plastic tank or oil pipes made of copper or aluminum. One of the most frequent breakdowns of the power steering is the failure of the pump: it is he who is subject to the greatest loads during the operation of the amplifier. It can fail as a result of untimely replacement of the amplifier fluid, which loses its properties during operation due to the appearance of impurities of metal shavings. Power steering assembly malfunctions are common as a result of vehicle operation with low power steering oil levels.

Video tutorial on what to do if the power steering pump howls

At different times, rotary, vane and piston pumps were installed on the machines, each of these designs has its own advantages and disadvantages.The rotary one has a high efficiency, but such designs have a very low resource, the piston one turned out to be expensive and rather whimsical in maintenance, therefore, it was the lamellar one that was most widespread.

The main pump malfunctions include:

leakage of working fluid through seal elements or oil seals;
noise and vibration as a result of bearing destruction;
decrease in discharge pressure.

Eliminating any of these faults will require removing the power steering from the vehicle. Do-it-yourself power steering pump repair is a rather difficult task, but it is quite a feasible task if you have the necessary tools and locksmith skills. Usually, there are no difficulties, we recommend using the vehicle operating instructions, as well as carefully writing down or photographing the sequence of the removal and disassembly process in order to avoid possible problems during its assembly. It is easier to remove the power steering from a car in which there is a lot of free space in the engine compartment, for example, a GAZelle, but to remove the power steering from an Audi 100 or Chevrolet Lanos car, especially with a 1.5-liter engine, considerable skill is required. In any case, after removal, the pump must be thoroughly flushed from external contamination, check the condition of the housing and make sure there are no cracks on it.

If the fluid level in the power steering reservoir decreases, this is a sign of a leak.

The power steering system is sealed, a decrease in the fluid level in the power steering reservoir necessarily indicates a leak. First you need to find the place from which the fluid is leaking. Very often, such a place is the elements of the pipe connection, a crack in a plastic oil tank. The most common place for fluid leaks is the power steering pump oil seal or its seals. Repairing such a malfunction will take a little time; to eliminate it, it is necessary to disassemble the pump and replace the worn-out seals and oil seals. It is worth paying attention to the condition of the shaft in the place where the oil seal is installed. If grooves or pits appear on it, then the gland will not fit snugly and leakage may reoccur. In this case, it is necessary to polish the shaft, but there are times when the wear is too great and it is not possible to achieve a tight seal of the oil seal, then installing an oil seal with a smaller inner diameter or replacing the shaft with a new one can help. In large cities, such as Moscow or St. Petersburg, there will be no problems with buying it, but in the provinces, the shaft will have to wait from several days to weeks, it is also worth considering the rather large price of this part from sellers.

Noise in the booster system can be caused by wear on the shaft bearings. If noise appears, it is necessary to eliminate it as quickly as possible, otherwise the shaft bearing may completely collapse, which will cause its misalignment, which in turn can cause severe damage to the housing. Very often, such a malfunction occurs due to excessive tension on the hydraulic pump belt, which as a result causes excessive stress in the bearings and leads to their destruction. You can also replace bearings yourself. First you need to remove the worn bearings, then press two new ones into the pump housing and cover, then put them on the shaft. When replacing bearings, be sure to replace the oil seals and gaskets.

The reasons for the decrease in pressure may be the wear of the ellipse of the inner cylinder or the rotor blades themselves, however, the resource of these parts is hundreds of thousands of kilometers, and sometimes they do not have to be changed at all during the entire operation period, as, for example, for Ford Fusion or Ford Focus 2. Much more A common cause of pressure loss is sharp burrs on the rotor that prevent the blades from working properly.As a result, they may not fully come out of their grooves or they may even jam, which will cause a decrease in pressure. The repair in this case is quite simple - it is necessary to process the sharp edges of the rotor at the point of attachment of the blades with sandpaper or a grindstone.
