Bmw e36 DIY steering rack repair

The bmw e36 gur system (power steering) is quite simple. It goes, as it were, apart from everything else, in contact with the engine at the attachment point of the power steering pump and with the steering shaft near the steering rack. Of course, the V-belt that turns the attachment on the engine also turns the power steering pump. The rest of the system is autonomous.

The power steering includes the pump mentioned above, the expander tank, the steering rack and the high pressure conductive hoses that connect it all. The meaning is that the engine pressurizes the steering rack, helping the driver turn the steering wheel, the expansion tank ensures that there is a constant fluid-filled circuit in the system, and the steering rack increases the driver's effort by converting the power steering fluid pressure into the desired vector depending on the direction of rotation steering wheel.

The weak point of the car, as many people think, forgetting that the car is no longer new, and this unit is under constant load. The BMW E36 steering rack is no better or worse than on other cars.

There are two types of power steering in cars - hydraulic and electric. we do not touch the second, and the first is the same for everyone and differs only on the basis of the design features of the car. The principle of operation has already been briefly announced - the redistribution of additional effort from a fluid under high pressure in the direction of turning the steering wheel. Hence the first conclusion - the car can safely drive, in the event of a power steering malfunction, it will only be harder to turn the steering wheel.

The next important point is that the currently old rail simply cannot but break. This is expressed primarily in smudges of oil under the car. determined visually. It is necessary to repair, since the oil must not flow out of the system, otherwise sooner or later everything will leak out, the circuit will become airy and there will be problems with the pump.

You won’t be able to repair it yourself - the maximum (and often the minimum) you need to remove yourself and give it to the workshop of turners and locksmiths.

Tips often have to be changed - they break from our expensive ones. You can do this yourself, and even without a pit - simply by turning the wheel and lifting the car from the working side with a jack.

The bmw e36 gur pump is attached to the engine in front from the lower right side, if you stand in front of the car. The tank, rail and pump are nearby.

Power steering pumps are not repaired, since the cost of repair is comparable to the cost of a new pump. Issue price from 50 USD for Chinese substitutes, up to 300 for a native BMW.

Trouble begins with the hum of the pump. If the hum is strong, looks like a rattle and reacts to the movement of the steering wheel, then the first thing to do is to check the fluid level in the hydraulic booster reservoir. If it's empty, add it and look for where it's leaking from (usually from the steering rack) Here is how to replace the power steering fluid.

In addition to the missing fluid in the system, air may occur, clogging of the line with debris (usually a filter) or weakening of the V-belt (the latter is unlikely). In any case, problems appear either with a characteristic hum from under the hood, or an increase in the load on the steering wheel in corners.

The repair consists first in replacing the power steering fluid, then, if the first did not help, replacing the pump and fluid.

oil is leaking from the steering rack where the steering wheel is attached. Is there some kind of oil seal? With a hydraulic booster.

Probably just need to change the sealing washers.

Is it possible to fix the leak yourself?

Of course it is possible, but this is provided that the hands grow from the right place. You buy a steering rack repair kit and change the whole thing.If my memory is correct, then you only need to replace the oil seals on the shaft, there are 8 of them. If there is a leak from the bolt that connects the g / y and the rail, then the replacement of the washers.

Do a Google search, there should be a detailed report.

people tell me who did it

I did it myself. If it flows from the rail itself, then I don’t advise you to climb inside it, since you need to know where to twist and turn. For example, here is a photo of a repair kit for you, if you can replace the whole thing, then go ahead.

rake also flowed. I took it apart and disassembled it, but not completely. flowed only on one side, which is shorter, bought a seal and replaced all the leaks for a year now. It is easy to disassemble, just do not confuse how to put the worm.

The steering racks on the famous "boomers" are those components that require regular complex repairs and maintenance. Fans of a “sporty” driving style are especially affected, but this should not be surprising, since the steering mechanism in such a situation experiences excessive loads.

Of course, the most important thing in repair is its cost. We did a little research and called both local "kuzmichi" and normal salons. The cost is about the same starts from 5,000 rubles, ending with 90,000 rubles.

And if you order rails on Ebee yourself and give them in the cabin, you can meet 20 thousand rubles. The rail itself will cost 15 thousand rubles, and the installation will cost 5 thousand rubles.

To repair these models, the steps should be similar. First, the rail is dismantled and cleaned of existing contaminants. After that, it is visually inspected and tested on a stand that artificially creates working conditions.

The repair itself may consist of replacing:

• faulty parts,
• bushings,
• seals,
• as well as surface grinding.

At the end of the work, the rail is mounted back, hydraulic fluid is poured in and tested. Sometimes such repairs can be done by yourself if the violations are minor. When grinding is necessary, a service center is indispensable.

1. We raise the car higher so that it is more convenient to work.
2. Drain the liquid.
3. We remove the wheels and unscrew the traction with levers.
4. Raise the engine.
5. We unscrew the pillows and the stretcher.

Then remove the rail, disconnecting the hoses. It only exits to the right.

We unscrew the thrust from the rail and wash it.

On the fives of the E60, the most sore point is connected with the rail:

Because of it appear clang and thud when crossing bumps. The repair consists of a complete disassembly, replacement of the bushings (and it is desirable for domestic realities to install not factory-made, but self-made ones with reinforcement), replacement of lubricants and fluids.

An example of a new and clean steering rack. Focus on them - it's better to pay a little extra than to buy the part again later.

Here is a video, maybe some tricks will help you:

Drain the liquid, then remove the rail. In general, we do everything according to the photo gallery:

Before removing the centering plastic sleeve from the worm, remember its location. Remove the retaining ring and unscrew the cap and nut of the worm. Dismantle the worm. On the right rack end, remove the flange having the gland and bushing. Install new parts in the same way.

A typical BMW E30 steering rack is small, like the car itself.

After removing the rack, pry off and unscrew the cover equipped with an adjusting screw. The bushings are pressed in by the factory, so you need to pick them out. It is better to change for home-made (from caprolon) on a sliding fit.

To fix them, drill a hole in the housing, cut the thread and screw in the lock. Fix the cover after punching installation.

Drive on good roads! No other way - the German made the car specifically for high-quality highways, not ours...

Therefore, BMW fans should think about the consequences of ill-conceived races over rugged terrain. So that.

Comments on article 5, leave your:

I still didn’t find a man, but your instruction helped my e36 boomer a lot!)))

Thank you for the detailed instructions with photos, otherwise I suffered with these rails. Of course, when buying X5 in 2004, I knew that I would run into some problems, but not with the steering wheel -))

Thank you very much for such a clear instruction, thanks to you I refrained from going to a car service and saved a lot of money, I recommend everyone to repair the steering racks on their own - there is nothing complicated about it.

As they say, the eyes are afraid, but the hands do =)

in general, it’s not safe to carry out such repair work yourself, it’s better to take the car for maintenance or to some kind of car service, than it will later turn out that restoring what you wised up there is three times more expensive than a simple rail repair

If knocks and leaks of the steering rack were noticed, do not rush to look for a new one, it is not difficult to repair it yourself.
Below, as an example, the repair of the Bmw e46 TRW rail is considered. The rail is quite old, this company does not make repair kits, it is difficult with spare parts, but there is one place where you can buy everything and cheap enough.
We drain the slurry, take off the rail, wash it, so that it would be easier to work.

Turn this nut clockwise. Only twist there very gently, literally by division or even half a division. And it is better to outline where he started to twist. In general, if there is a working out in a worm or a shaft, then it will not help there, you squeeze the rail, it will spin harder, but the backlash will not really go away, and the pump will pump harder and it can die.

There was the same garbage with a fat, a tightening does not help, I tried it for myself, the restoration of the rail solved the issue. I won't say anything about turning. Knocking can cause worn bushings and tightening has nothing to do with them. It is better to give the rail for restoration or try to find a live one.

Reiku bu is a cat in a poke, I changed the reiku and it passed me as many as 5 thousand km and rattled, although it was removed from the car with low mileage. Previously, they cost 100 tanks, that is, 800-1000 UAH, which was normal, now they are asking from 2500 and there are no guarantees, you can arrange a storage of rails in the garage. Repair costs 2000 UAH. Those who normally restore, change everything there, check it under pressure and give a guarantee, they gave me 40 thousand. If the shaft of the khan, they don’t even take it for repairs.Well, so everyone decides for himself.

BMW steering rack repair. If you notice knocks or leaks in the steering rack, do not immediately run to a car service and install a new one, try to repair it yourself. In this article, we will consider the procedure for repairing the steering rack using the BMW e46 as an example.

The main factors indicating the presence of malfunctions of the BMW steering rack are considered to be a characteristic knock from the front or right side of the suspension or an oil leak. When these signs appear, do not panic ahead of time. The cause of the noise may be the simple loosening of the rail from external influences. Such a defect is corrected by a banal adjustment of a special screw. The cause of the leak may be a worn steering rack oil seal, which is not difficult to replace.

Dismantling the steering gear

If the above signs are found, the nature of the breakdown should be identified. Before starting the BMW steering rack repair procedure (as a car equipped with airbags), first lock the wheels in the “straight” position, then remove the ignition key from the lock. Ignoring this requirement can lead to damage to the loop that signals the driver's airbag, up to its rupture.

We dismantle the steering mechanism, for this:

1. We put the car on a viewing ditch or lift.
2. Pump out the fluid from the power steering reservoir.
3. We dismantle the front wheels and remove the tie rod ends.
4. We unscrew the nuts and bolts holding the shaft and body bracket and remove the bracket together with the steering wheel and shafts.
5. Unscrewing the nuts from the side of the hood, we separate the steering gear from the front of the body.
6. We feed the steering mechanism forward until the gear comes out of the front of the body.
7. Remove the steering gear by pulling it in the direction of the right wheel.
All dismantled parts must be rinsed, you can blow it with compressed air.

We drain the liquid, remove the rail, thoroughly wash it, in particular, in order to make it easier to find defects.

We unscrew all the parts that can be unscrewed.

On the right you will see a retaining ring, remove it.

On top of the worm, we take out the plastic centering sleeve (be sure to remember its position) and see the retaining ring, remove it. We unscrew the cap from below, then the worm nut and carefully knock it out.

Then, at the right end of the rail, we begin to slowly remove the flange with the bushing and the stuffing box, pulling the shaft towards ourselves.

Removing the seal and bushing

We install new parts in the same way. I pressed it in with my hands, resting the flange on the table.
We clean the rail inside with gasoline. There is another oil seal in the center of the rail, I knocked it out with a long-handled screwdriver. A new oil seal can be installed in two ways: with a shaft or a head (you need to wrap it with paper tape to avoid damage to the mirror). In our case, the second method was used, it seemed more practical and convenient.

If there are defects on the worm or on the shaft, rubbing (belt) from seals, these places should be polished with abrasive sandpaper 2000. The piston rings (let's call them that) on the shaft and worm, in my case, were in good condition, so I did not touch them .

We replace oil seals, fluoroplastic (kaprolon) elements with new ones from rem. Kit, and also lubricate the bearings with pentosin.

Now we begin to insert the shaft, wrapping the teeth with paper tape in advance, so we do not damage the inner oil seal. There are two ways to wrap the teeth: lubricate them a little with pentosin or oil and wind the tape. Thus, we get a kind of cover that can be easily removed. Or we glue paper tape with a strip in several layers on the gear part of the shaft.

It's time to insert the worm. If necessary, it can be rotated 180 degrees if there are signs of wear (in my case, I did not turn it over). To do this, as I indicated above, it is necessary to remember (mark) the position of the plastic guide of the worm.

Be sure to treat the gear pair with new grease.I lubricated with bright green Kastrol lithol, in theory it should contain lithium additives. The price is about 300 rubles.
