Do-it-yourself Daewoo Nexia steering rack repair with gur

It's time to repair the steering rack with power steering on the Nexia. Reasons for repair: knocking when driving through small irregularities and when shaking the steering wheel from side to side. Steering tips and tie rods are normal. Pulling up 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 socket wrench for “12”, the head is inconvenient, it does not fit on the nut (the length of the stud does not allow).

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

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

Assemble in reverse order.

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 you tighten the steering gear in time, the mileage before overhauling the steering gear 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:

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

We hang 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.

1. If you remove it, then we can more accurately adjust the gap between the rail and the plunger.
2. 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.
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 key of 26. 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 a 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 or go around the pits in front of the pits, 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:

1. Initial inspection of the mechanism's performance on the car.
2. Diagnostics after removing the mechanism, checking the backlash, integrity of oil seals, bushings and bearings.
3. 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:

1. The main task is to tighten the adjusting screw, which is located in the end cover of the steering gear.
2. To carry out this manipulation, you will need a garage pit, and if it is not there, then use a jack.
3. Before operating the jack, the wheels of the machine must be set in a straight position.
4. The steering wheel play can be measured with a play meter. The indicator should not exceed 10 ° (this is what GOST says).
5. The 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 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.)

To adjust the steering rack, Daewoo Nexia should hang the front wheel on a jack. Then install the metal bar from the side of the wheel arch along the tie rod and rest against the end of the castellated nut. This will release 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 another shape - and the rail wears out. Therefore, it is easy to drive in a straight line, but difficult to corner. Secondly, the contact surface wears out. Concentric circles are formed there, and the saddle under the slider on the rail is also broken. The runner gets loose and the plastic pad on it wears out.

You can restore the steering rack of Daewoo Nexia like this. First, restore the section to a 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 irregularities to a smooth surface. Thus, the frictional force between the slider and the rail will increase. The plastics are removed from the slider. Two strips of sandpaper are placed under it, 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 PIOL grease is placed inside the body. Now there are no control problems, no knocking.

If the problem with the Daewoo Nexia steering rack is that the gur liquid begins to flow from the steering rack into the salon, then you can figure it out in this way. Dismantle the steering rack, the cover of the steering column switches, first unscrew the steering shaft cross. Carefully remove the circlip that is interfering with the steering gear bearing. It can be removed with some effort. Then find a 40x20x6 oil seal. And replace it. You can also buy an oil seal in the steering rack repair kit.

how to adjust the steering rack - Chassis, steering, brakes, tires and wheels Daewoo Nexia - Nexia club - Yekaterinburg

On 16 (probably on 8, I don’t know either), although it doesn’t require it, it is regulated. They take a long armature with a sharpened bent end, turn the steering wheel to the right until it stops and through the hole in the left wing behind the wheel, where the thrust comes out, stick this armature.
With the bent end, they fall into the slot (slot) on the nut and pull or loosen. This is, if not removing.

However, as the conversations show, the rattling of the rail (namely the rail, not the shaft) is a disease, the treatment of which costs from 10 rubles by replacing the rail, which is not an option, because the new rail can be just as sick.

And if you tighten the nut, in the fight against rattling, the steering wheel may stop returning.

Why doesn't the key fit? Fits.
There is a locking nut, in which there are slots on the slot. It is unscrewed as I wrote above.
A nut similar to the large nut for the top bearing of the handlebar fork.

And unscrew the gemorno with the key due to the fact that you can't just crawl.

Bryakaet - there are many options, both the rail and, for example, the rear silent levers.

If there is a suspicion of a rail, then you can check this (at least I checked it this way):
On a cold one, i.e. after a sufficiently long parking, turn the steering wheel, as the play is checked, a little more. In principle, nothing should be blurred, tk. the grease is cold and “heavy”.
After warming up and driving (the lubricant has warmed up), try the same thing - such dull clicks or dull knocks will appear, which means the rail.

I have just a cold blur much less!

Traffic safety depends on the good condition of many components and assemblies of the vehicle. The steering is no exception, in particular its main part is the steering rack. Not only safety depends on its technical condition, but also comfortable control of the machine. Unfortunately, this high-quality assembly sometimes fails. Because of what this happens and what is required from the driver in this case, we will analyze in more detail.

The operation of a serviceable rail occurs imperceptibly for the driver. With the occurrence of a malfunction in it, it becomes tangible. Every driver will pay attention to abnormalities in the operation of the car that suddenly appear.

About malfunctions

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.
