DIY steering rack repair

In detail: do-it-yourself steering rack repair from a real master for the site my.housecope.com.

The dextron ran from the MMC Delica steering rack.
Initially, in order not to bother, I purchased the "Power Steering Tuning" fluid. She, of course, helped, but not for long, only for a year, after a year of driving, the dextron started running again.
I drove to the service station and then with what agility the master agreed to repair the rail for fifty bucks, in just half a day, I was a little embarrassed, I got the impression that removing the steering rack, work for a ruble, and you have to pay ten.
Without thinking twice, I decided to try to repair it myself.

It turned out that the repair is really not very difficult, but experience is still needed.
I will not describe those touching moments when I gained this very experience for three days. In general, the three-hour work cost me three days of wasted time and the same fifty bucks for damaged oil seals, which had to be changed twice.
But the experience is always good, albeit a bad one.
In general, I decided to write an article, after reading which, I hope, you will avoid the mistakes that I made.

The rail can be repaired without a viewing hole, but it is better, of course, from a viewing hole or a lift.

An innovative idea allows you to cheaply repair the steering rack with your own hands. Those who wish are given the opportunity to learn from experience and, using available materials, improve this part of the mechanism of their car.

This video provides information on the innovative idea and the use of materials at home when troubleshooting steering rack problems at home. A non-standard approach to eliminating extraneous sounds while driving, delights in its simplicity and results. This solution will allow you to forget about the knocking steering rack for a long time.

For everyone who wants to watch the original repair of the steering rack with their own hands, the video clip provides such an opportunity. Troubleshooting steps for the device that controls the movement of the wheels and the direction of the vehicle include:

unscrewing the bolts and squeezing out the clamps with the steering wheel unscrewed with a 22 mm spanner wrench;
removing the bushings and unscrewing the bolt on the steering column in the passenger compartment in the area of the pedals with a 14 mm wrench;
removing clamps from the steering rack and removing the device through the wheel;
releasing the steering rack from thin clamps using an awl and a thin screwdriver and an anther;
preparation of several pieces of plastic from watering cans, cans and other products to fill the free space between the metal rail body and the support sleeve. The size of the blanks must correspond to the length and width of the recess for the sleeve to move;
inserting blanks inside the steering rack until it stops against the bushing, among which the last element should be the most rigid;
checking the free movement of the sleeve over the plastic, tightly installed in the rack cavity;
installation of the steering rack in place.

This solution eliminates the knock of the support sleeve for a long period of time.

The gearbox of the hydraulic power steering wheel (steering rack) is responsible for organizing the turns of the vehicle. This mechanism is an integral part both for cars with hydraulic power steering and for cars without hydraulics. The steering column serves as a connecting element between the steering wheel and the wheelbase, so its role in the safe operation of the vehicle cannot be overestimated.The parts of the steering rack wear out quickly enough, because take on the main part of the load that is transferred to the car during cornering, when hitting any type of obstacle, when the wheelbase hits potholes and holes in the roadway. Do-it-yourself steering rack repair may often be required.To prevent failure of the steering rack, a technical inspection of the vehicle should be periodically carried out, which allows you to identify all faults at an early stage.The main signs indicating the appearance of deviations in the operation of the gearbox:

The presence of knocks in the gearbox, transmitted through the steering wheel of the vehicle;

An increase in the effort that the driver needs to apply to the steering wheel to turn it;

Extraneous noise arising during the operation of the hydraulic booster pump;

The presence of a backlash in the steering rack, which is felt when turning the steering wheel;

Traces of oil leaking from the hydraulic power steering.

Steering rack flowing with power steering

Any of the listed symptoms signals a malfunction that must be eliminated immediately. Lack of timely work can adversely affect the operational life of the mechanism, up to its complete failure.

If a problem is found, the car can be handed over to a car service specialist or the steering rack can be repaired with your own hands. It should be noted that self-elimination of defects requires certain knowledge about the device of the vehicle and some tools necessary for disassembling the steering rack.

Details

To fully repair the steering rack, you should have the following spare parts and tools on hand:

a special repair kit consisting of all the parts necessary for the steering rack;

corrugation;
gear shaft;
bearing;
lubricating mixture.
octahedron key at 17;
tools for mounting and dismounting bearings;
set of wrenches.

For the highest quality repairs, it is advisable to use an overpass or inspection pit.

First of all, the vehicle should be driven onto an overpass or inspection pit, after which, with the help of jacks, the vehicle should be raised and the engine protection (if present) and wheels should be dismantled. Next, you need to remove the heat-insulating plate of the gearbox and unscrew the nuts of the ends of the steering rods, which are knocked out of the ears with a hammer.The next stage consists of disconnecting the pipeline followed by a liquid removal procedure. To do this, you need to start the car engine, and then make several turns with the steering wheel in different directions. The process is completed by removing the fasteners located on the hydraulic power steering gearbox. After dismantling, the mechanism is securely fixed in a vice and cleaned of dust and dirt, which inevitably accumulate on parts during the movement of the car.

Dismantling the steering rack

After the completion of work on the disassembly of the steering rack, all the constituent elements of the mechanism are thoroughly washed from the oil and dirt deposited on them. Then the parts are subject to a thorough visual inspection for the presence of mechanical damage arising during the operation of the vehicle. Parts with serious defects must be replaced with new ones. In some cases, due to severe damage, it is advisable to completely replace the steering rack. Assemble the steering rack in the reverse order.

There are no significant differences between repairing the steering rack of cars with and without hydraulic power steering. Only bushings and compositions of fluids used to lubricate parts of the mechanism will be different.

After carrying out all the above-described work, it is recommended to carry out the diagnostic procedure for wheel alignment.

The total time it takes to repair the steering rack varies from two to three hours. These repair work refers to work of an average degree of complexity, which, with certain knowledge and skills, it is quite possible to carry out even a novice car enthusiast who has patience and perseverance in achieving a specific task.

Often, the culprit for the failure of the rail is the power steering pump. When the valve sinks, excessive pressure is created in the rail and the oil seals begin to flow. You can replace the rack with a new one and after a month, if the power steering pump is faulty, the new rack will also fail.If the power steering tank is empty, and you do not know what to fill in there, we do not recommend moving on our own or pouring any liquid there. Better to use the tow truck service.Each car has a device such as a steering rack.Its main function is to turn the wheels in different directions when the car is moving. It is necessary to periodically inspect the steering mechanism in order to save yourself from serious breakdowns and emergencies in the future.The steering rack is connected to the wheels of the car by means of ball ends. The features of the steering rack are directly influenced by the type of control - hydraulic and mechanical. The mechanical type is often found on domestic cars, as well as on some old foreign cars. Hydraulic, basically, is only in the design of imported cars.All car parts are subject to wear and tear. But most of all this applies to the steering rack mechanism. It is her mechanism that takes all the shocks, collisions into deep pits that arise from irregularities on the roads. No matter how careful you are a driver, a breakdown will happen sooner or later.

To determine if the steering rack is broken and if it needs to be repaired, you need to make sure that the rest of the chassis is in good working order. This can be done at any specialized car service. When identifying certain causes of breakdowns in the chassis of the car, it is best to eliminate them on the spot, not postponing until tomorrow.

The main signs of a breakdown or malfunction in the steering rack should be learned like two or two - this knowledge will save you a lot of trouble. So, often problems in the rack are given by a significant increase in efforts when turning the steering wheel. For hydraulic vehicles, the fluid level must be constantly monitored and, if necessary, topped up.

If the vehicle is hydraulically controlled, there may be a loud noise or abnormal noise in the power steering pump when cornering. While driving, an unpleasant knock may appear, which gives a lot to the steering wheel. Slight play may appear when the steering wheel is turned. It appears regardless of which way you turn the steering wheel.

The most common sign of a breakdown is a slight leakage of oil, this phenomenon is typical for both types of vehicle control. The reason for this breakdown is the wear of the steering rack oil seal. If such reasons appear, repairs must be made immediately so that your vehicle control mechanism does not completely fail while driving.

It is much easier to repair a steering rack for a car with a mechanical type of control than in the case of a hydraulic one. We will consider an example of replacing and repairing a hydraulic type of control, since in this case you will learn about all the possible difficulties. First you need to figure out what elements the steering rack consists of.The main components are the toothed shaft, bearing bush and slide valve mechanism. In a hydraulic type mechanism, a pump is attached to the steering rack, which directly drives it. By the way, it gets in the way when removing the rail. Repairing the steering rack is very difficult. If you have never performed this procedure, then it is better to contact a car service or a knowledgeable friend who will help you do the basic operations.In addition to knowledge, you will need a number of tools and spare parts - ready-made repair kits are sold specifically for work. It has its own for each car model. But some elements are suitable for a car of the same brand - this often happens in the case of domestic cars. When the repair kit is purchased, you can start disassembling the rail. This is best done on a lift or on a viewing pit. Image - Do-it-yourself steering rack repair

First you need to lock the steering wheel straight and put the car on the handbrake. You can fix the steering wheel using the locking mechanism, or by wrapping it with sealing tape along with the steering column. The next step is to remove the engine protection, if you have one. After that, unscrew the fasteners - fold them separately so that during the assembly stage you do not lose them and do not get confused.

Under the hood, if necessary, remove the air filter by moving the pipes to the side. Disable electronic chips that can interfere with the removal of the steering rack. If you have a hydraulic control system, then you must first pump out all the liquid from the tank. Nowadays, it is very expensive, so the savings will not hurt you - carefully pump it into a clean canister.

Inside the car, you need to unscrew and then knock out the cam mechanism. The high and low pressure pipes in the hydraulic booster must be unscrewed with a special wrench so as not to "lick" the edges. Under no circumstances try to rip them off with other tools at hand. This can lead to the need to completely replace them, and for this the tubes will need to be expanded. You cannot do this at home, therefore you will have to contact a specialized service, so that all your savings will come to naught.

The cam mechanism is located near the gas and brake pedals. As soon as you remove it, the rail with all its mechanisms and bearings can be pulled out of the car. During the dismantling process, complications may arise with the steering rods and ball ends, it may be necessary to unscrew them. But best of all, if you take them out with the rail, because new anthers will be much more convenient to install when everything is assembled.

The next step is to disassemble the steering rack mechanism and replace parts. At this stage, it is very important to remember the correct location of all parts and the order of their removal. Use a screwdriver to unscrew the plastic cap on the gear shaft. After that, you need to unscrew the lock nut, do it carefully so as not to rip off the thread. If necessary, lubricate the threaded connections. Next, use a flat screwdriver to remove the retaining ring and the lower rail seal. Image - Do-it-yourself steering rack repair

Using a hammer, you need to remove the locking pin, because it blocks access to the upper stuffing box. In most cases, it is necessary to replace the upper oil seal of the steering rack - it is he who wears out the most during operation, the most of the load is applied to the mechanism of its bearing. The steering rack oil seal is located together with the bearing on the steering universal joint. It is necessary to remove the oil seal together with the bearing and then knock it out using a suitable type of wrench.
