Repairing a steering rack or power steering gear, as it is also called, is an important matter - you need to be able to do it yourself. Why? Because if there is a malfunction of the steering rack, then there is a failure of the steering, and this can turn into a disaster on the road. To prevent this from happening, you need to know how to repair a steering rack.

The principle of operation is the same, but there are some differences in the design. I must admit that the work is quite difficult - before starting it, you need to know the steering rack device.

Further, the installation proceeds in the reverse order.

As seen, DIY steering rack repair it is quite within the power of a person who is familiar with repairs in general terms. By the way, mechanical and hydraulic steering racks, which are much more common than their modern counterpart, the electronic steering rack, are subject to self-repair. The latter needs a special setting, which is better to entrust to professionals.

The repair is completed, the result is satisfied, of course, when I put it, my opinion may change, but so far the feeling of a new steering rack does not disappear.

In fact, nothing complicated. Useful tools: open-end and spanner wrenches (12 ″, 14 ″, 17 ″, 19 ″, 22 ″, 24 ″, 27 ″, 32 ″), vise, flat and Phillips screwdriver, pliers, turnkey nut (like 24 ″ ) later I will write for what, a hammer, a wooden spacer, a lot of rags.The repair kit itself is also required.

Most of the time is spent on cleaning the rail from dirt, maybe someone will have it differently, but I had it all in oil mixed with dust.

We begin disassembly by removing the steering rods. To do this, remove the anthers (they are on 2 clamps) and move them towards the steering tips. We see the lock washer between the rail and the rod. We bend it back with a screwdriver and use a different tool to try to unscrew them from each other. I did it with a vise and a 22 ″ wrench. We do the same with the second side.

After that, you need to unscrew the two large nuts (marked in the photo). To do this, we unscrew the lock nut. I did this again with the help of a vice, simply holding the lock nut in them and turning the rail. You can try to do the same using some huge key, but I didn't have it. Further, using the same 24 "nut, or rather inserting it inside the large hex nuts, unscrew it with a regular wrench. We carefully take out the insides. Under one there will be the lower bearing, under the other block, which aligns the rail inside the casing.

Then we unscrew the tubes from the top and the top cover (on two bolts). It is removed quite easily. We see the following.

We take out the "worm", if it does not work by hand, then you can gently hit the stock from the bottom side.

Next, remove the retaining ring from the long side of the rack casing.
Now you can knock out the rail itself. On the short side of the casing, we begin to knock on the rail with a hammer through the wooden spacer. The metal stopper should be knocked out from the back side. Now, if you have enough strength, you can simply pull from the long side and the rail will come out with two oil seals and two washers, you will figure it out on the spot. If something remains inside, then again tap the rest from the short side to the long one.

We carefully clean everything from a mixture of grease and dextron.

And we start replacing old parts.

What was in the kit:
4 small Teflon rings, changeable on the "worm"
1 large teflon ring, and a small rubber o-ring - change in the middle of the rail itself
2 identical oil seals along the edges of the rail, in the same place washer-limiters
2 different oil seals with "worm" upper and lower
1 large o-ring - under the top cover
small air vents at the joints of the tubes with different places

We start assembly in the reverse order. We put on washers and seals on the rail, lubricating them and the rings with dextron, and the rail slots with lithol. We carefully hammer it into the casing from the long side, then put a metal stop and a retaining ring. On top of the casing we drive in the lower oil seal of the "worm" and carefully insert it itself, with the replaced rings and put on the bearing and upper oil seal, as well as the splines lubricated with lithol. Lubricate the top of the "worm" (up to the lower gland) with dextron and put on the top cover. We tighten it with bolts, because difficult to put on. Then we turn over the rail and tighten those large nuts with all the insides, after having lubricated it with lithol. It remains to screw the rods into place by placing new lock washers, not forgetting to roll them.

Look like that's it. The main thing is not to be afraid and remember what, where, how and most importantly why it was filmed, so that you can put everything in its place.

Symptoms: knocks in the steering rack, manifested when driving through small irregularities (disease of all korollopodobnye with electric power steering).
Diagnosis of servicemen - replacing the rail (in practice, it does not help out for long and costs a lot).
Solution: replacing anything in the rail that can knock. And there are only two places knocking in such rails - the adjusting unit and in the area of ​​the bushing located at the opposite end of the rail (in the case of right-hand drive cars - the left side of the rail). And since nothing needs to be changed in the adjusting unit, all repairs are reduced to replacing the factory bushing with a custom-made one.

Patients: Will VS 2002 1.5 L (electric power steering!)

We climb into the pedal assembly and remove the protection from the steering shaft, unscrew it by hand, and remove it easily:

We completely unscrew the bolt securing the intermediate shaft to the crosspiece:

IMPORTANT! Put the wheels straight, remove the key from the ignition, lock the steering wheel. This is done in order to prevent, after removing the rack, turning the steering wheel by a number of revolutions more than it should be. Otherwise, a break in the wires of the "snail" of the airbag and the resulting malfunction of the latter are inevitable.

We hang out in front of the car and throw off the wheels (front enough).

Next is the removal of the steering rack. It has been proven from our own experience that it is possible to unscrew the rail fasteners without additional disassembly, but pulling out the rail is very time consuming. Do not waste time, twist the stretcher - you will save a lot of time and effort.

But first - the steering tips: take out the cotter pin, unscrew the nut, hit the place indicated below with a sharp, biting hammer blow, and the finger falls out by itself (we do it with both sides

We unscrew the subframe, 4 bolts to the body, 3 bolts in the area of ​​the rear engine mount and 3 nuts in the same place.

After that, the subframe, together with the rack, gently (if you planned to unscrew the last bolt correctly) lowers and hangs on the levers and the anti-roll bar. Everything - the rail at a glance: unscrew:

We remove and carry to the workbench

Let's start disassembling it:

10) Unscrew the left rod from the rail using keys 29 and 22.

11) On the back side, we loosen the large clamp and detach the boot.

12) Take the rolling pin out of the rail, put it aside.

15) On the new sleeve, we make a longitudinal cut necessary for its compression and setting in place. We orient the cut in the direction of the car's movement - in this direction the rail experiences the least stress.

16) Lubricate the sleeve and gently straighten the sleeve, check the fit of the sleeve with the free end of the rolling pin.

17) Press in the aluminum washer with a suitable head. Insert the rolling pin into place. We insert the shaft into place, for this, with a 22 key, we swing the rolling pin around its axis and at the same time push the shaft - at a certain moment the gears are aligned and the shaft falls through. We tighten the clamping sleeve of the shaft until it stops, we counter it with a lock nut. We assemble the adjusting unit, tighten the adjusting cup until it stops and release it by 90 degrees, counter nut with a counter nut. Subsequently, the tightening torque can be adjusted on the machine after a test drive with a certain skill, the mechanism must be tightened until the steering wheel returns to the straight position when exiting the turn. Pull into place, anthers into place, tighten. Rail for stretcher, stretcher for cars. Near the rear (in relation to the rear of the car) fastenings of the subframe to the body there are holes on the body and on the subframe, the combination of which excludes the removal of the caster. (holes in the photo)

We pull everything in and climb into the salon.There we loosen the upper crosspiece, move the shaft between the crosspieces up and put the lower crosspiece on the intermediate shaft. We are tightening everything. Subsequently, you can similarly align the steering wheel if, when driving straight, the steering wheel looks slightly to the side.
