DIY Toyota Corolla rail repair

In detail: do-it-yourself repair of the Toyota Corolla rail from a real master for the site my.housecope.com.

I want to raise a long-standing topic, which may not be as relevant for 150 Corolla as for 120, because according to my own observations on Corolla 150 it is the rake that does not bother so much. Mainly the steering column, both flaps. nevertheless, I want to share, because the topic of steering racks, including their repair and lubrication, is relevant: officially, the rack is not repaired or serviced, but is quite expensive. In addition, there are no separate steering rods on sale, if we talk about the "original" ones.

The advice was shared by a person who works in a taxi company in Vladivostok, which acquired many of our Corollas at one time, in fact, he operated them with decent mileage.
This was not the only useful practical advice I read about. The author presented to the court a photo report on the implementation of this generally simple technique. I have just brought it up a bit to make it easy to read and download.

I will make a reservation right away that experts in the usefulness of the "oil dish" side differed in opinion. I can voice some arguments, some not Copenhagen.
In general, I invite you to discuss.

I will immediately add three points, I read the opinions:
1. The grease used in the report, TOTALLY unsuitable for Toyota steering racks
2. Too much of it was injected.
3. Tie-in made, slightly in the wrong place.

With the first I completely agree, the other two I am not ready to either confirm or dispute.

I can add from my experience in repair / lubrication of the rack on my previous car - KIA C'eed. Here are the generalized methods that I used taken from the KIA C'eed forum:

Video (click to play).

So everything that is described here takes place on most modern cars, both classmates and an auto class higher than Toyta. Before drilling the rail itself, first check the steering gear crosses that are in the cabin (if I am not mistaken, there are 2 of them), as well as the telescopic tube (it is responsible for adjusting the steering wheel for departure), in most cases it knocks there. It is also not uncommon for the plant to install crosses with increased backlash, which begin to knock after a few hundred kilometers, it also happens that the bolts fixing the crosses turn away or weaken (not all manufacturers counter them, oddly enough). The racks themselves usually begin to knock when the mileage is over 100-120 thousand km (I will make a reservation for everyone in different ways), this knock usually manifests itself when driving through pits and combs and has a dull but loud sound, while on the steering wheel it is usually not reflected in any way, that is, no knocks are felt on the steering wheel.

About lubrication. The lubricant AZMOL FIOL-1 was used, as recommended for this type of work. FIOL-1 is an NLGI 1 grade grease, i.e. has a lower viscosity at low temperatures compared to universal greases of the Litol group (NLGI 2), which undoubtedly has a positive effect on further operation. Otherwise, these greases are identical.
About the volume. 150 grams of grease on each side is quite enough (two oil cans were put). It is not necessary to hammer the entire rail to the eyeballs, the air flow inside must be maintained.

As a result, I concluded that greasing the rack does not help for long, I drove about 20 thousand after lubrication, then I simply changed the rack.
1.replacing the rail
2.Steering rack grease (Fiol-1)
4.screwing the bolt into the EUR to increase the force on the output shaft (dumb, tight steering wheel)

Undoubtedly. Separate one from the other. It's easy to do it on the pit :)
As for the Corolla 150, most of the knocks come from there, and not from the reiki itself. The rail itself knocks on the RAV-4, and on Outlenlers, and on Highlanders, and right from the salon.
On Corollas, if the rake knocks, it also knocks right away. Or a little later. As far as I read, the replacement under warranty did not give anything, in general, the author also writes about this.
On the indicated runs, knocking is already wear and tear during operation. It certainly cannot be cured by anything other than the manufacture of fluoroplastic bushings (I think this topic is familiar to you).
Knocks in the steering column, there is a place to be due to unscrewing and on the Corolla, as correctly noted, it is very simple to fix it, pulling up without any disassembly.
The intermediate shaft crosses, responsible for adjusting the overhang), cannot be treated in any way, this is for sure 🙂
There is another crash-safe folding countershaft under the hood, the same story. Two cardan shafts, and a knock at the splined joint of the folding shaft.
Also, discard the knock from the steering tips (which, in general, does not happen with the Corolla right away at low mileage), and most importantly from the bushings and anti-roll bar struts, the knocks from which are very often confused with the rail itself.

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.

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:
1) Remove the rubber boot.

2) Take the 12 key and unscrew the bolt shown in the photo.

3) Remove the intermediate shaft.

4) Unscrew the lock nut (used a gas wrench)

5) Unscrew the clamping cup of the rack shaft.

6) Then we put on and fix the intermediate shaft again, then take out the entire shaft with the bearing with a light blow with a copper hammer on it.

7) Turning the rail over, disassemble the adjusting unit: unscrew the lock nut with a 41 key

8) Then we unscrew the adjusting cup using any flat object, take out the spring and the pressure piston.

9) Remove the left anther, very carefully so as not to break (we draw inside along the circumference of the anther with a non-sharp object)

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.

13) We look at the rail from the left end - we see an aluminum hold-down washer, behind it is the notorious bushing.

14) We hook the washer with a hook and knock it out, then take out the sleeve.

Here it is - the sleeve, because of which all the ailments. )

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)

Image - DIY Toyota Corolla rail repairTips to the levers, set the wheels straight, the steering wheel is straight from the very beginning. 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.

Some Toyota Corolla drivers complain that when driving on uneven roads, a knock is heard somewhere in the steering wheel area, while not noticing any visual manifestations of a malfunction. As a rule, this sound signals the need for repair of a steering rack Toyota Corolla. If you start to notice this kind, we advise you to start repairing as soon as possible: it is known that any problem is easier to fix in the early stages. This also applies to car malfunctions.

If there are any problems in the human body, then he notifies about it with the help of symptoms. A car is also a kind of organism that, in the event of a malfunction, sends signals to its owner. So, by what signs can you determine the malfunction of the steering rack?

Steering rack device diagram

  • A characteristic knock from the steering (this is a consequence of an increase in backlash - a gap at the junction of the steering rack and rod);
  • Leakage of fluid from the power steering (the reason is damage to the boot and corrosion of the oil seal, a possible consequence is corrosion of the shaft);
  • Feeling of vibration when turning the steering wheel;
  • Inaccuracy in control (the reason is shaft deformation);
  • Biting the steering wheel (after turning, the steering wheel does not return to its original position).

If you regularly observe these symptoms, we advise you to contact a service center to tighten the rail. Otherwise, the amplitudes of the backlash will increase, the knocking will become louder, which will lead to mechanical destruction of the part. The car will be less responsive to control, which can create a difficult road situation. However, the destruction of the rail is a rather long process, however, you must agree that constant knocking does not contribute to a pleasant trip, irritating and distracting the driver.

You can fix the problem of increasing backlash at any Toyota service center. You can try to fix the problem yourself, fortunately, there are a lot of materials on the Internet dedicated to how to tighten the steering rack on Toyota Corolla... However, this method of solving the problem is fraught with some nuances and is suitable only for drivers who have at least minimal experience in repairing their iron horse.

  • wear of the steering column bracket bearing;
  • failure of the shaft cross bearings;
  • weakening of the tightness of the connection between the bracket and the cross.

First of all, you should try to determine the location of the malfunction, that is, to determine exactly where the backlash has increased. This can be done during a visual inspection: probe all connections and test the vehicle in motion. Then, when the problem is localized, you can start disassembling the mechanism.

  1. First of all, the car must be immobilized. Place it on the handbrake and, for reliability, install anti-rollback devices under the rear wheels.
  1. Remove the plastic trim from the steering wheel and remove the steering wheel.
  1. Remove the protective plate - when you do this, you will see the nut. Unscrew it and remove the steering wheel mounted on the shaft.
  1. Free the steering column: unscrew the bracket bolts and the steering gear, remove the boot.
  1. After the column is removed, you can proceed to repair of a steering rack Toyota Corolla 150... Examine it carefully for malfunctioning bearings and a cross, loose connections. Tighten loose connections, replace faulty parts with new ones.
  1. Assembling the mechanism back, carry out the above manipulations in reverse order.

For Toyota Corolla 120 cars, the most common way to repair a rail is to replace a bushing. This is due to the high cost of the new part (about 20 thousand rubles). Usually, steering rack bushing Toyota Corolla 120 have to be ordered from a turner due to the almost complete absence of these in the free sale.

Before undertaking repairs, we advise you to familiarize yourself with the device of the part. Getting down to repair of the steering rack on your Toyota Corolla 102, do not forget to read videodedicated to her device.

Steering racks Toyota Corolla How to repair the steering rack on your own Toyota Corolla photo report Full and detailed description of the rather complicated process of repairing the steering rack with the creation of a new bushing

LABELS for search engines: TOYOTA COROLLA TOYOTA COROLLA STEERING RACK REPAIR STEERING RACK E12 E12 Hello everyone again! So the promised photo report on the repair of the steering rack is ready. Let the “old-timers” forgive me for repetitions, but in the photo report I have collected all the information necessary to repair the rail, starting with the drawing of the bushing and ending with the final adjustment. All "landmarks" right-left, front-rear are given relative to the driver.

All photos, including the special keys and bushings, are posted in the photo gallery. If the “followers” ​​have any questions, then before asking them, read the previous messages. Maybe there are already answers for example: We need a special key for disassembling and adjusting the steering rack. And the steering rack bushing, made according to this drawing or ordered by the forum member Makar: Dimensions 24.9 mm; 31.1 mm; 32 mm must be made with the maximum possible accuracy and minimum roughness.

Ideally, the marks from the turning tool should be virtually indistinguishable. I would like to draw your attention to the dimensions of the sleeve, namely the diameters of 24.9 mm and 31.1 mm. Moreover, it is useful to decrease the inner diameter and increase the outer diameter by 0. Therefore, STRICTLY adhere to the dimensions of the sleeve as shown in the drawing. Further, the bushing must be reworked: 6 longitudinal cuts are made on the bushing with a hacksaw for metal, with a depth of approx. Then, with a clerical knife, we expand the cuts and give them a wedge shape, see.

We make one cut over the entire length of the sleeve and expand it by approx. This cut, when installed in the rail, must be positioned at the top and make sure that it does not fill with grease. It should look something like this: Before starting work, be sure to disconnect the battery. The first step is to remove the steering shaft cardan, while remembering that the so-called “snail” SRS AIRBAG is installed in the steering column, designed for 5 full revolutions: If exceeded, it will break and the “SRS” light will turn on.

When installing, after setting the wheels straight ahead, “open” the ignition switch and turning the steering wheel now to the right into a straight position - I throw on the cardan.

I check the number of turns left and right, if necessary, rearrange the cardan. As a result, the steering bar in the extreme positions becomes vertical, I don’t remember the number of revolutions, I just set the symmetry, and accordingly, the turning radius to the right and left will be the same.

Also, do not forget to unfasten the boot latches, it will look something like this: When working, follow safety precautions. And it's better to work together. To remove the steering rack, do the following: Unpin the nuts securing the steering tips to the steering knuckle, and with a sharp hammer blow, disconnect the steering tip.

When working, observe safety precautions, in particular, when unscrewing the bolts in the movement "away from you", keep your palm open, in this case, if the key comes off, you will not bump your fingers, oh, how many of them were broken In red and yellow circles, those bolts which must be unscrewed on the dorestyle.
