Do-it-yourself steering rack repair on a Nexia without a gur

It's time to repair the steering rack with power steering on the Nexia. Reasons for repair: knocking when driving through small bumps and when shaking the steering wheel from side to side. Steering tips and steering rods are normal. Tightening the steering rods and the rack itself did not bring the desired results - there is no play in the area where the rods are attached, and when pulling up, the knock is even stronger and the steering wheel turns harder.

We unscrew the two bolts and unscrew the two nuts securing the steering rack to the body. To do this, I used a tubular socket wrench on “12”, the head is inconvenient, it does not fit on the nut (the length of the stud does not allow).

We take out the rail through the opening in the right wheel arch, but for this we had to remove the steering rod completely, with the steering tip

Diagnosis of damage: good performance on the worm shaft. Some grind off the top of the teeth, but we do not recommend doing this - it is better to either find a new shaft (or in good condition), or give it to familiar turners for manufacturing.

Reassemble in reverse order

Automotive steering rack has been used in the construction of cars for a long time. Without this detail, transport management becomes impossible. With the development of technological progress, mechanical steering racks began to be replaced by hydraulic and electric ones. The steering rack, which is part of the Daewoo Nexia mechanism, is used together with the power steering (power steering). This mechanism reduces the mechanical effort of the driver when driving.

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

The rack consists of the following parts:

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

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 enter 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.

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

Important! Every 50-60 thousand kilometers, 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 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 in front of the car.

There can be many signs of a steering gear failure. 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 the gearbox needs repair:

• When turning the car, you have to turn the steering wheel a lot.
• At high speed, it starts to throw the steering wheel and skid to the sides.
• When driving on uneven terrain, a knock and recoil into the steering wheel begins when it is in its central position, when cornering, the recoil disappears.
• General decline of hydraulic fluid in the system.
• After entering the turn, the wheels of the car do not return to their original position.
• While 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 a breakdown, the steering rack of your Daewoo Nexia can become completely faulty at high speed, and this entails sad consequences.

The main reason for the wear of steering racks in our country should be considered poor-quality roads. The service life of your gearbox is directly proportional to the quality of the roads. If you don’t slow down or go around them in front of the pits, over time you will feel the characteristic knock of the front axle, which will become the first signal of a malfunction.

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

Another option for a gearbox failure is considered to be a winter “drift”. When the wheels are turned out and at the same time do not make revolutions, they give out an enormous load on the crankcase and shaft. In this case, there is a risk of damage to the seals and anthers, as a result, dirt begins to get inside the system, which eventually destroys the entire mechanism. It is also worth remembering that you need to regularly change the hydraulic fluid in the system.

According to statistics, the most frequent repairs of the steering Daewoo Nexia occur due to wear of the slider, seals and stem. Often, failure occurs due to knocking in bearings that experience regular shock. Bearing imbalance impairs correct operation of the gearbox.

Diagnosis of the Nexia rail should be carried out in three stages:

1. Initial inspection of the operability of the mechanism on the car.
2. Diagnostics after removing the mechanism, checking the backlash, the integrity of seals, bushings and bearings.
3. Detailed inspection of all components of the steering gear.

At the first stage, we must make sure which mechanism failed. Is there a breakdown in the auxiliary mechanisms. It is necessary to 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 several times in different directions, this reduces the risk of damage to the steering mechanism.

At the second stage, the entire mechanism must be clamped in a vise. Next, check the wear on the teeth in the worm pair. Be sure to make sure that rust does not appear on the steering rod apples. All this is done in order to understand whether a complete replacement of the rack or only part of its mechanism is needed.

At 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. You can eliminate the backlash by first tightening the gearbox.

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

Did you know? The first power steering patent was issued in the UK in 1902. Frederick Lanchester became its legal owner.

And yet, it is worth tightening the rail (you will 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 the following plan:

1. The main task is to tighten the adjusting screw, which is located in the end cap of the steering mechanism.
2. To carry out this manipulation, you will need a garage pit, and if it is not there, then use a jack.
3. Before actuating the jack, the wheels of the machine must be set in a straight position.
4. Steering wheel play can be measured with a backlash meter. The indicator should not exceed 10 ° (as GOST says).
5. Tightening should be done slowly.After scrolling a little, you need to check if the play on the steering wheel has disappeared.
6. Check the car in dynamics, if at speed you feel heaviness in corners, you will need to loosen the adjusting screw.

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

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

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

Repair of the steering rack in the workshop is as follows:

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 contact the 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:

• Check the condition of the anthers and seals. Their damage is the first step to the breakdown of the entire mechanism.
• When turning the steering wheel to the extreme position, do not leave it like that for more than 5 seconds. Do not give the engine high speeds when the steering wheel is fully unscrewed. 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 make sure 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 follow these tips, then the longest possible operation of the mechanism without repair will be ensured.

Daewoo Nexia, like every car, simply must have weak points. One of them is the steering rack. Knocking and rattling when driving will please few people, 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 rail begins to knock. Regardless of whether the car is with or without hydraulic booster. 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 be saved only by repair or a complete replacement.

Tightening eliminates excess clearance between the gear and rack.

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

1. We park the car on a level surface.
2. We substitute under the rear wheels recoil.
3. We tear off the bolts of the left wheel.
4. We hang out the left side and remove the wheel.
5. Turn the steering wheel all the way to the right.
6. 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, we will remove the vacuum brake booster for adjustment.

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

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

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

Diagnosis: working out on a worm shaft, although maybe it should look like this, but it's somehow not great.

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

This is how the shaft looked like after processing.

Assembly in reverse order.

After assembly, the steering wheel became 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: It may help for a while, but it's not an option. I plan to replace my rail, but it’s expensive with the power steering, I’ll install it without a gur, hence the question, what to do with the pump?
Maybe if you keep the rail in a slightly overtightened state (the area of ​​​​adhesion of the teeth is larger), then it takes longer, but not a fact, the metal on the shaft is very soft.

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

To adjust the steering rack Daewoo Nexia, hang the front wheel on a jack. Then install a metal rod from the side of the wheel arch along the steering rod and rest against the end of the castellated nut. This will loosen the nut.

The Daewoo Nexia steering rack wears out in several places. First, where it is supported by the saddle. The section turns from a circle into a different figure - and the rail wears out. Therefore, it is easy to control in a straight line, but hard in corners. Secondly, the contact surface wears out. Concentric circles are formed there, and the saddle is also broken under the slider on the rail. The slider becomes loose and the plastic lining on it wears out.

You can restore the steering rack of a Daewoo Nexia like this. At the beginning, restore the section to the circle. You will need a lathe. Next, polish the section. Spread the skin on a flat surface, put the slider with the worn surface down. Then you need to grind the bumps to a smooth surface. Thus, the friction force between the slider and the rack will increase. The plastic is removed from the slider. Under it are placed two strips of skin, which was used for grinding, plastic is put on. Now the plastic part will not move so freely between the aluminum walls of the Daewoo Nexia steering rack housing. Then FIOL lubricant is placed inside the case. Now there are no control problems, no knocking.

If the problem with the Daewoo Nexia steering rack is that the gur liquid starts to flow from the steering rack into the passenger compartment, then you can sort it out in this way. Disassemble the steering rack, the cover of the steering column switches, first unscrew the steering shaft crosspiece. Carefully remove the circlip that interferes with the steering gear bearing. It can be removed with some effort. Then find an oil seal measuring 40x20x6. And replace it. Also, the oil seal can be bought in the steering rack repair kit.

With a run of approximately 500 km. tapping appeared in the area of ​​​​the steering rack only when driving over bumps such as crushed stone and small potholes. At the service, the rack was tightened for the first time, it was after 100-200 km.the same thing happened again. They said that it makes no sense to tighten it up, since the car is without GuRa and the bushings in the rail are to blame for everything - it seems like this is a long-standing flaw in the factory. They suggested replacing the bushings made of a different material, they said that the new ones would last longer. then it’s a pity to give the car to smoke to the Uzbeks. If anyone had a similar one, let me know. Thank you all in advance.

Was it not a pity to give them money for the car?

As I understand it, you still have it under warranty, so demand a replacement rail.

In general, it is strange how it is without GUR.

andrey80 don’t worry too much, today I dismantled the steering rack on my Ksenia, and so the bushings there are normal, the whole point is that there is a double bushing called points, I replaced it, it’s dry inside, the lubricant swelled, and yet, it was installed a little skewed, Uzbeks in one word, but in auto services these homemade products will tell you, is there a normal familiar auto mechanic? Then there will be no problems to repair for a penny.

Hello dear car enthusiasts! Sooner or later, the time comes when it is necessary to repair the steering rack with power steering (GUR). In order to figure out how to sort out the steering rack using a living example, and not “on the fingers”, we will consider the procedure for performing this work using the example of a Nexia car.

The principle of the device of the steering rack, almost any car, is no different. Naturally, there are nuances and features of the constructive nature and type of placement of the steering rack on the car. It is to clarify these features of the steering of your car that there is a manual from the manufacturer.

The reasons for the need to repair the steering rack are simple: the appearance of a knock when driving through bumps in the road and when the steering wheel swings rhythmically to the sides while driving, when steering play appears.

Before proceeding with the repair of the steering rack, be sure to check the steering tips and the condition of the steering rods. If they are normal, you can try to tighten the steering rack.

In the absence of the desired results, you should check for play in the area of ​​\u200b\u200battaching the rods. When tightening the rods, the knock can become even stronger, and the steering wheel will spin harder. And, if all efforts to adjust the steering gear were in vain, then we can move on to the question of how to sort out the steering rack?

For many novice motorists who are trying to do car repairs with their own hands, the question arises - where to start and how to disassemble the steering rack.

And you need to start by studying the manual for servicing your car, or technical literature, which is now offered in abundance in technical bookstores, but most often on the Internet.

You should also purchase a repair kit in advance to restore the steering mechanism. And, of course, it is necessary to prepare an appropriate set of tools that may be required during the repair process.

It should include a set of wrenches: open-end and socket wrenches, as well as a time-tested lubricant such as Litol. Although today the market offers steering rack lubricant, the basis for all lubricants is, in principle, the same.

You just need to remember that the steering rack lubricant must correspond to the temperature regime of the region in which your car is operated.

If a motorist performs the operation of disassembling the steering rack for the first time, it is advisable for him to stock up on a skilled assistant who, at the right moment, can supply the necessary tool or support the assembly that is on weight. So, let's start disassembling the steering rack:

• Before starting work, you need to set the steering wheel to the middle position and mark the current position of the shaft with a marker or chalk. This must be done, since during assembly it will be easier to determine which shaft tooth to put on the rail;
• Drain the oil, for which unscrew the tubes suitable for the rail in front.After that, attach the tubes in place. Now you need to unscrew the propeller shaft bolt and remove the rail from the cross member;
• Steering gear components must be washed thoroughly, for example with engine cleaner. It is more convenient to do further disassembly of the rail on the table.
• To replace the upper repair kit, you need to pull the bearing off the shaft.
• To replace the bottom set, remove the wire stopper by rotating the bushing on the rack shaft.
• In the center of the rail housing there is a cuff and a washer, they must be replaced. When pressing new parts, do not damage the corner edge of the cuff.
• During installation and assembly, you need to check the correct entry of the shaft into the rail, then put the cardan shaft on the splines, while pulling the rail to the cross member.
• Now you should check that the steering wheel is in the middle position, then the rail can be fully assembled and carefully fastened.

As a rule, the most common diagnosis of damage is a significant wear of the worm shaft. It should be replaced with a new one. Assembly should be done in the reverse order of disassembly.

Based on the results of the steering rack repair, you see that the steering rack bulkhead – not too complicated procedure. In conclusion, I would like to remind fans of fast driving: shaft wear could be less if the driver carefully overcomes uneven areas, monitors tire inflation and performs timely vehicle inspection and preventive maintenance.

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, the hands do not get tired. But, like any other, moreover, a rather complex and highly loaded 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 greater the effort). The hydraulic assembly consists of a double-sided cylinder with a piston, it is connected directly to the steering arms.

During rectilinear movement, the oil in the system constantly circulates in a circle without creating pressure on the piston. But turning the steering wheel also shifts the rotary valve, which changes the distribution of oil on the two sides of the piston. On one side, the pressure is pumped, and from the other, the oil is pumped into the reservoir. The increased hydraulic pressure shifts the piston, which presses on the steering arm and removes some of the force from the steering wheel.

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

Hydraulic Power Steering Pump for Daewoo Nexia

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

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

Daewoo Nexia has two standard places for leakage from the power steering: 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 hoses and their connections, and the pump itself, then it will have to be disassembled and the gaskets changed.And if a leak is found in the area of ​​\u200b\u200bthe pedal assembly, then you need to buy a set of new oil seals and replace it.

Another common problem is pump failure. There can be many reasons, but the pump is simple in design, easy to disassemble, and you can either replace it completely or purchase individual parts.

Belt leading to power steering pump on Daewoo Nexia

Also, when turning the steering wheel on the Daewoo Nexia, noise or whistling may appear. Such a 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 decided by replacement. If it's not the belt, then it's worth checking the pump bearing.

The power steering requires some 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 Nexia owner community agreed that the fluid needs to be changed every 50 thousand mileage.

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

When replacing, you need to raise it in 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 the oil does not flood the entire engine compartment. But motorists recommend buying a rubber bulb at a pharmacy and pumping oil out of the tank with it, and only then disconnect the hoses, so there are fewer risks.

Power steering fluid change Daewoo Nexia

After the oil is drained, the system hoses must be immediately placed in a collection vessel 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.

The removed tank is best washed with ordinary gasoline. It is worth noting that there is a filter inside the Nexia tank, it cannot be pulled out, but it can be unscrewed and rinsed 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 again from lock to lock, some of the oil will go away and you will need to add more, and then turn the steering wheel again. If the level drops again, top up again to max (the fluid level should be checked with the wheels aligned). But that's not all, after the oil is filled in - you need to start the car and turn the steering wheel again from lock to lock and check the level again.
