Toyota Corolla steering rack - design

A mechanical assembly consisting of a gear is designed to convert the rotation of the steering wheel into horizontal deflection of the vehicle's front wheels. The design itself consists of several elements, the coordinated work of which ensures the movement of the vehicle:

1. Frame. Designed to accommodate the component parts of the unit. The body material in modern passenger cars can be made of steel, aluminum or duralumin. The hydraulic cylinder is located either inside or outside the steering rack housing.
2. Shaft. For the manufacture of the shaft, high-strength steel is used, the surface layer of which undergoes a cementing procedure. Thanks to the shaft, power is transmitted to the wheels.
3. Support bushings. To keep the shaft from distortion, special bushings are used. They fix the device, centering it in the body.
4. Distributor. When turning the steering wheel, force must be transmitted in a certain direction. To do this, you need a distributor, through which the flow of hydraulic fluid is directed to the required compartment of the hydraulic cylinder.
5. Bearings. The rotation of the elements in the housing is ensured by bearings.
6. Pistons. The hydraulic fluid pressure is transmitted to the steering shaft by the pistons.
7. Oil seals. Sealing elements are used to retain hydraulic fluid inside the device. They transfer fluid flow to the desired compartment of the hydraulic cylinder, preventing it from moving into other cavities.
8. Clamping mechanism. Required to keep the shaft from moving and regulates the force.
9. Hydraulic bolts. Fixation of the support bushings and the clamping mechanism is ensured by the presence of locking rings, springs, and hydraulic bolts.
10. Rings made of rubber and Teflon. These elements are used to seal all rack units.

Hmm... based on the drawing www.drive2.ru/l/473534095511519452/ Just the same, 81 is not correct... and 44 is the plane! But it's better to read the comment below. very well written. Foil for the original bushing, and new bearings. It’s just that we haven’t been able to break the chetop yet... This fluoroplastic is in the firebox. Did you manage to remove the original bushing without damaging it? . Did you remove the rack?

The original bushing can be removed without problems using 2 self-tapping screws. The wall thickness of the bushing removed from the rack is greater than that of the new LM6044. What's the point of installing such a bushing? The catalog says bushing LM6044 is installed on FIAT 500//// Internal diameter 26 mm External diameter 32.8 mm Height/Depth 24.5 mm Material plastic Wall thickness (32.8-26)/2=3.4 mm.

Yes, I thought maybe there is a need to immediately tighten the clamping sleeve or is it not there like on a dry rack? Or change the seals right away. Doesn't the steering wheel turn tighter in winter?

I didn’t tighten or change anything, the rail took the contract. Her condition was visually good. In winter, the steering wheel will not be any harder to turn.

Hello! How is your hydraulic rack? Have any problems surfaced? How to spin in winter? Has it become noticeably tighter compared to the electric one?

Hello. I've already sold the car. But there were no complaints, no problems, and what kind of problems there could be)) it turns just as easily, I didn’t notice any obvious changes in the force!

Toyota Corolla steering rack - the main causes of breakage and wear of the racks

The main reason why car enthusiasts turn to our car service center due to rack wear is the poor quality of the road surface.

Damage to an important component is also affected by proper driving. For example, if the driver does not slow down before potholes on the road, the steering rack will quickly fail, letting you know about the malfunction with a knock.

Hydraulic steering racks deteriorate if the driver is used to leaving his car with the wheels turned out in the winter.

Premature wear is also possible if the hydraulic fluid is changed infrequently.

The tightness of the assembly depends on the integrity of the anthers, so dust and dirt should not be allowed to get inside the rack, which can lead to wear of the seals and leakage.

Violation of vehicle operation rules affects the operating condition of the steering rack. When servicing your car, it is very important to use high-quality components and working fluid, as well as to undergo maintenance on time.

Carrying out diagnostics and repair work at a trusted car service center is a guarantee that the mechanism will not fail due to unqualified repairs.

Another reason for control failure is often a change in the operating functions of the wheels. For example, incorrect tire pressure, bearing wear, balancing.

Cost of the original product and its analogues

The price of the original steering rack for this car model ranges from 20 to 45 thousand rubles. If you purchase a used spare part at a dismantling station, its price will depend on the condition. For a part from a damaged car you will have to pay 14-15 thousand rubles.

According to car owners, such a part can last about 120-140 thousand kilometers until it needs replacement. If you buy a rack from a foreign car dismantling shop, the cost will be from 6 to 15 thousand rubles.

In the accompanying documentation you can always find information about the mileage of the car from which the spare part was removed. This information will make it possible to navigate the feasibility of purchasing the part and its condition.

How to diagnose faults

If you are interested in Toyota Corolla steering rack price, then you have found any signs of malfunction indicating that the rack has failed. But, before you decide to replace or repair the Toyota Corolla rack, you need to diagnose the faults.

Diagnosis of the steering condition is carried out in three stages.

The first includes inspecting the car, eliminating damage to the chassis and checking all auxiliary components and mechanisms. This diagnostic stage is carried out in accordance with a certain sequence in order to identify the malfunction as quickly as possible.

Next, the removed element is diagnosed, knocking and play are determined. This work shows specialists whether the Corolla steering column can be repaired or whether a complete rack replacement is required. The device is clamped in a vice to check the steering rods, the backlash of the support sleeve and other nuances.

The final stage of verification is a detailed inspection. It is carried out after complete disassembly of the mechanism.

Our technicians check every detail to make a final decision about the condition of the device and draw up a list of repairs.

Repair or replacement

Each case is individual. It should be understood this way: if the mechanism is subject to restoration - repair, in all other situations - complete replacement with new consumables. In order to achieve partial savings, you can combine repair and replacement. The exact dimensions of the spare parts are indicated in the operating instructions, where there is a graphic drawing of the steering element.

Based on the results of a comprehensive diagnostic, a list of necessary new spare parts, consumables, repair kits for seals, and rubber products is compiled, and preparations for repairs begin.

Steering rack Corolla 150 - adjustment

This procedure can only be carried out in a specialized garage with a pit. To operate, you will need a key designed to adjust the unit. The vehicle is securely secured and its wheels are in a straight position.

Using a backlash meter, the gap is measured, which should not exceed ten degrees. The rack is tightened using a screw located in the end cover of the mechanism. The location of the screw is specified in the car's passport.

The rack is adjusted at a leisurely pace. At the same time, the movement of the steering wheel, the amount of play and knocking in the column are constantly checked. After finishing the work, you need to test the chassis. If heavy wheel movement is observed, the adjusting screw is released.

The result of the adjustment should be the complete disappearance of knocking or play. In addition, free rotation of the wheel to the standard central position must be achieved.

Toyota Corolla steering rack repair

Before the troubleshooting procedure, any remaining oil and dirt is removed from the steering rack. This is done using technical fluid. After disassembly, the elements (bushings, rings, power seals) are replaced. Repairs may include turning work, which is performed on a grinding machine. On it the shaft is ground and polished to a mirror finish.

Any repair work is completed by assembly with control of the necessary factory parameters. At a special diagnostic stand, specialists check the characteristics of the unit and then install the rack in its original place. Next, the power steering system is washed, oil is added, and the system is pumped.

Useful tips for Toyota car owners

Some tips from car enthusiasts may be useful to prevent steering rack failure and premature wear:

• you need to monitor the condition of the anthers;
• do not hold the steering wheel in the extreme position for more than five seconds;
• in the winter season, you should not turn the steering wheel immediately after warming up the engine, but should turn it with smooth, short movements. These steps will help warm up the oil in the power steering system;
• It is advisable to personally supervise all work performed at the service station;
• Do not rev the engine if the steering wheel is in the extreme position. This can lead to increased load on the rack parts or wear on the power steering pump.

Since the steering rack is an important part of the machine, repairing the unit must be approached with all responsibility. Every vehicle owner must take care of timely diagnostics of the car, because in the event of a steering malfunction, the driver and passengers are at risk.

Replacing the bushing: step-by-step instructions

The process of replacing the bushing is not very complicated. First of all, the car must be driven into the garage, since repairs will take some time. So let's get started. We remove the steering column panel - this is very simple, we need to unscrew all the bolts and remove it from the latches. As a rule, it is held on by three bolts. After this, we remove part of the air vent - which does not interfere with washing - there will be a lot of dust in it.

After our workplace has been prepared, we unscrew everything that prevents us from removing the steering column. When this work has been done, we use a marker to mark the position of the column that we will need to establish during its final collection. So, the column is removed - we do it carefully, since it weighs a lot. In the photo below we will see the place without the column, as well as the column itself and its bushing in an approximate version.

Next, we need to put something soft on the floor, for example, foam rubber and a rag on top of it. Next, on the prepared surface, with the steering wheel down, we place the steering column itself. You won't be able to pull the bushing out by hand. Therefore, we screw several screws into it - they will serve as a support for us to further pull it out. When the self-tapping screws are not fully screwed in, cover the steering wheel with a rag and rest your feet on it, and with your hands, using pliers, pull the sleeve by the self-tapping screws. After some effort, it will come out of its place. In the photo you will see that the bushing is no longer there.

Next, we need to clean the shaft from old grease and dirt. After cleaning, treat it with new lubricant and install the new part in its place.

As a rule, after replacing it, the knocking disappears, but if the crosspiece is in order. If it was broken or worn out, it also needs to be replaced. Now it's time to replace the cross.
