Replacement of steering rack. Repair of steering rack

Often in various forums devoted to automatics, you can meet complaints of car owners to knock on the steering wheel. In this case, the best option is to replace the steering rack. Let's look at how this part works, typical faults, and discuss the possibilities of repair.

How is the control gear arranged?

This part performs the function of communication between the steering wheel and the wheels of the car. With this part, the force from the steering wheel is transferred to the wheels of the car, and as a result, the car turns.

The reducer is connected to the wheels by means of the steering rods, as well as the tips. This is a gear part . The gear, which is fixed to the shaft of the column, is in mesh with the teeth on the rack. When the shaft rotates, the gear moves this gear piece to the side.

In most cases, the design of the control gear consists of a shaft, seals, anthers, o-rings. You can see what the steering rack looks like . The photo can be seen below.

Typical malfunctions

In the first place among the failures is a knock. This is the nastiest and most unpleasant for the motorist of all of those sounds that are heard from under the front axle of the car. At first, this knock is barely noticeable, but then its intensity is constantly increasing. Then, after a while, these knocks are given in hands. After a few months, riding on uneven roads becomes like death. The steering wheel twitches in his hands like a wounded beast.

It is interesting that all this manifests itself only on small road potholes. But the car penetrates deep pits quietly. This is the first sign that repairs to the steering rack are necessary.

Another popular feature is the tight work of the mechanism. It happens that the steering wheel is very tight in only one direction. After a brief parking under the car, you can observe the oil puddle and the characteristic hum in the GUR. All these signals to what soon becomes a machine impossible to manage. This applies to hydraulic mechanisms. The cause of such malfunctions are seals, which have become unusable.

There is one more malfunction. This is backlash. You can feel it with your hands. The steering wheel can move freely to the right and left when driving at low speed. At the same time, the sharpness and sensitivity of the reactions to the driver's influence is necessarily lost. Among the reasons for this can be identified the broken corner of the teeth of the reduction gear and gear, the vertical free running of the bearing, worn out silent blocks, and other mechanical damages. Here the best solution is to replace the steering rack.

Another highlight is the poor return of the steering wheel to the central neutral position. Here, most likely, the shaft, the gear reducer itself, or its crankcase is deformed.

Self-diagnosis

In order to know exactly whether you need a complete replacement of the steering rack, or you can get by with a simple repair, it is worthwhile to conduct small diagnostic measures. It's easy to do it yourself.

Repair and adjustment can be dispensed with if you hear a normal knock. Diagnostic procedures require the removal of the steering wheel. Then you should pull the shaft up and down. If there is a distinct movement, it means that there is no lubrication in the rack bearing.

You can also check the contact level of the gear and gear reducer, as well as the possible backlash in the bushing. This is done with a sufficiently reliable grip, as well as the place where the traction is connected. This is done as follows. The joint is found under the hood and the shaft is pulled. If the movements are slow, then the knots are loose, it's not scary. If all these actions are accompanied by a terrible screeching and knocking, then - it's bad. Repair of the steering rack is unavoidable.

You have three options to save the details and return to your auto manageability. This purchase of repair kit and independent repair work, a trip to the service station, as well as there is another radical solution - the replacement of the steering rack entirely with all giblets.

If there is a certain amount of money, then, of course, it is best to install a completely new part. Restoration in the SRT will be a little cheaper, but there is no guarantee that the reducer is enough. Self-repair is cheaper, but requires the purchase of a repair kit. Is the replacement of the steering rack expensive? The price of this work for VAZ is 1500 rubles, plus add another price for the new part. It turns out a round sum.

Sleeve of the steering reducer

In the design of the reducer there is a special bushing. If you feel a significant increase in effort to turn the steering wheel, if you notice a stitch from the mechanism, if the steering wheel is clearly knocked on, if there is a play when the steering wheel is in operation, then the steering rack bushing needs to be replaced.

The replacement process

Professionals in car repair do not recommend performing independent repairs of this plan, because this mechanism has a complex design, and for some operations a specific tool may be needed. We will not listen to experts. After all, for repair work is enough for a regular set of tools, which can easily be found in any garage, as well as a repair kit.

The repair kit includes anthers, as well as oil seals, clamps, corrugated rings.

How to disassemble the rail?

Doing this work alone is very difficult. This work should be done with a friend, a neighbor, yes with anyone. A partner is necessary at the first steps. It is then necessary to dismantle and disassemble the steering gear.

The first thing to do is to remove the right tire cover, but rather the wheel completely. In the next step, unscrew the nut from the tip. If the nut is difficult to give, try to soak it in the WD-40. Further turn the steering wheel all the way to the left.

So, using a flat screwdriver, the reducer must be disconnected from the rods. To work it was more convenient, it is necessary to raise the car a little. At the next step, remove the plastic plug and unscrew the lock nut. The retaining rings must also be removed and then the shaft and packing can be removed from below. The upper seal can only be removed after the pin that holds it is removed.

After all these actions, the locking ring is removed, then the gear reducer, and now it is easily and simply dismantled plastic sleeve and stuffing box.

Accessories will be in dirt and oil, so you need to clean them thoroughly. After cleaning, you can inspect and inspect. Sleeve should be changed necessarily, if it is seriously worked. The bushing usually breaks down due to corrosive processes.

We replace the bushing

This is not difficult, but it does not always work the first time. You need to work carefully. Inserting a fresh bushing in the seat is not too convenient. The body of this part has a semi-circular flat shape. Here in this form and you need to get special "ears" on the bushing. It is also more convenient to do it together. A partner can work as a rudder - then the part will go easier.

After installation, the sleeve should be well lubricated. To do this, you can use a special tool or use an ordinary lithol. Then, after assembling and setting the thrust, the hinges also need a lot of lubrication.

Replacing the anther of the steering rack

This small detail prevents water, dirt and dust from entering this mechanism. As you use this anther can become unusable, for example, tear - then it needs to be changed. Understand that this protective casing is torn, it turns out not always. In order to make sure that the anther is intact, you should turn the steering wheel all the way to the right and inspect the part we are interested in. Then - the same, but turn all the way to the left.

The steering wheel should be rotated because it moves the traction and the gear part. Together with these elements, the protective cover also deforms.

So, let's try to replace the part without the need for dismantling. To do this, remove the air filter, so that it then does not interfere with us. Also, disconnect the water outlet. Now unscrew the mechanism protection. This is simply done by twisting several nuts M10.

Then, with the 20 wrench, unscrew the rods and remove them, unscrew the yoke, which fastens the mechanism to the body of the car. Knit screeds from the extreme sides of the anther and remove it.

Now the cleaning stage. It should be cleaned and lubricated thoroughly. You can use a grease for the shrus, lithol or graphite grease. Before installing a new anther, lubricate the inside. After all, it moves along with the drafts. Put it on the rail and make sure it moves freely. Then twist it all back.

Replacement of steering rack 2110th VAZ

On the example of VAZ 2110 let's see how this design is being replaced. Removing the rail is the simplest part of the job. To do this, unscrew the bolt holding the coupling. You will find it under the pedals. Here you need the key to 13. Next - move to the engine compartment. Here, unscrew the nuts that attach the whole structure to the body. Then push the mechanism forward until the fastener comes out. Now the part can be reached through the wheel arch. It remains only to install a new part and assemble in the reverse order.
