Extraneous knocks when driving on rough roads, disappearing in turns, indicate a steering malfunction. If repair or adjustment of the VAZ-2114 steering rack is not possible, then it will need to be replaced. Approximately how much it will cost depends on the amount of work - a new steering rack costs about 3 thousand rubles, the cost of replacement - from 1,200 rubles.
Tools
To save on repair costs and change the steering rack yourself, you will need the following tools:
Key on 13, 17, 19;
- mounting blade;
- screwdriver;
- a hammer;
- jack.
Steering rack replacement
Place the car on a level ground, tighten the parking brake lever and place blocks or special stops under the rear wheels. The front wheels must point in the direction of straight ahead. Disconnect the terminals and remove the battery.
Jack up the front of the car, jack up the car and remove the wheels. Clean and lubricate the steering rack threads with WD-40 to help loosen the nuts.
Inside the passenger compartment, it is necessary to unscrew the bolt that secures the intermediate shaft of the steering column to the steering gear shaft. Loosen the tie rod bolts with a large screwdriver or spudger by prying off the ends of the lock plate. Turn away bolts and disconnect steering drafts.
After installing a new rack, it is imperative to lock the steering rod mounting bolts by bending the edges of the locking plate.
Remove the 4 nuts, two on each side, and remove the mounting brackets from the steering rubber pads. Disconnect the steering gear shaft from the steering shaft. Remove the rack through the cutout in the right wheel well.
Install the new mechanism in reverse order. At the beginning of the installation, you need to make sure that the steering rack is in the middle position. The marks on the crankcase of the mechanism and the anther must match, the flat on the gear shaft must be on the right.
To check the correct position, you can move the rack in any direction until it stops, then make one full turn of the mark on the anther in the other direction, then combine this mark with the mark on the steering gear housing.
Be sure to check the correct wheel alignment after completing all installation work.
The installation of corners is carried out by specialists on a computer stand, this operation must be performed in order to avoid rapid tire wear.
A characteristic knock may indicate a malfunction of the steering rack, especially when cornering. How to change the steering rack VAZ 2114 is shown in this photo report, if available necessary tool do-it-yourself replacement is possible.
Signs of failure of the steering rack VAZ 2114
The steering rack is a prefabricated assembly consisting of many parts, where the failure of at least one entails the inevitable breakdown of the steering rack. Therefore, it is important to determine the breakdown by the first signs.
- An experienced driver should immediately note that turning the steering wheel became more difficult or periodically steering wheel starts to wobble. The reason for this may be the failure of parts of the ball rods or the telescopic rack.
- Also one of the signs of a malfunction is large steering wheel play due to play in the rail itself. In addition, the backlash tends to increase during operation, which jeopardizes the safety of driving a car.
- There is a "recoil on the steering wheel" accompanied by noise in the front suspension. This may be due to an increase in the gap between the rail stop and its nut.
- Visible oil leaks on the rack, with a simultaneous increase in efforts to rotate the steering wheel, accompanied by noise in the rail area, also indicate a malfunction of the rail and oil leakage.
- For the convenience of performing subsequent work, we take out the battery and adsorber.
- Inside the passenger compartment, unscrew the bolt securing the intermediate shaft of the steering column from the shaft of the steering gear drive gear.
- In the engine compartment, disconnect the tie rods from the swivel arms.
- On both sides, unscrew the two nuts securing the steering mechanism.
- We disconnect the drive shaft from the steering shaft and take out the steering gear through the hole in the steering rod, having previously jacked up the car so that the rack lever does not interfere with extraction.
- Install the steering gear in the reverse order of removal.
When installing the steering, the rack is set to the middle position, that is, the marks on the anther and crankcase must match, the mark on the gear shaft must be on the right. In case of turning the gear, it is necessary to move the rack to the stop in one of the sides.
To replace the steering rack VAZ 2114 you will need:
- liquid WD-40;
- open-end wrench "for 13", "for 22", "for 19";
- ratchet with a head "for 13", "for 17", "for 22";
- chisel and screwdriver, mount, jack;
- new rail VAZ 2114.
The price of a standard rail VAZ 2114 from the manufacturer VAZ with article number 21080340001210 will be about 3,100 rubles. You can also purchase its analogue from the manufacturer TRIALLI with the article CR108 for 2300 rubles, and the company FENOX with the article SR1600207 - 3400 rubles.
The average cost of a spare part is indicated for the spring of 2017 in Moscow and the region.
Replacing the steering rack on the VAZ-2113, 2114, 2115
The steering rack is used to transfer the turning force from the steering wheel to the front wheels of the machine. In VAZ 2114 cars, it is not equipped with either hydraulic or electric booster, and has an exclusively mechanical design.
The principle of this design is that the force from the steering wheel is transmitted through the steering shaft with a drive gear at the end to a rack with a gear drive.
When the steering wheel is turned, the rack moves horizontally in a certain direction, and turns the wheels through the steering rods.
The steering rack is located in the engine compartment on the rear side of the engine, and is attached to the partition between it and the cabin with clamps.
Faults
The reasons for the failure of the steering rack can be:
- spent resource;
- regular driving on rough roads;
- sharp accelerations of the car with the steering wheel turned to the extreme position;
- mechanical damage due to wheels falling into deep pits or a traffic accident.
Symptoms of a failed steering rack:
- knocking in the area of \u200b\u200bthe rack when turning the steering wheel;
- difficult steering wheel (“biting” or jamming);
- vibration and knocking while driving;
- increased steering play;
- wheel alignment violations (determined by uneven tire wear).
When to change the steering rack
The listed malfunctions of the rail require its immediate repair or replacement. If this is not done, steering can fail at any time, endangering the lives of the driver and passengers of the car.
There are three options for troubleshooting the steering rack:
- adjustment (performed after a complete diagnosis if the rail does not require repair or replacement);
- repair (includes replacement of the repair kit);
- replacement of the entire assembly (involves the installation of a new rail with or without rods).
If a faulty steering rack has a resource of more than 100 thousand kilometers, a repair kit is not always able to change the situation for the better. In this case, it needs to be replaced.
The price of the steering rack and its replacement
The cost of the steering rack for a VAZ 2114 car is from 2300 to 3500 rubles. The average price for work on replacing it at a service station is 1200 rubles.
The catalog number of the standard steering rack with rods for the VAZ 2114 is 2108-3400012 or 21080-3400120-00.
Replacement
If you decide to replace the rail with your own hands, invite someone you know to help you. An assistant is required in this process. Prepare also the following tools and means:
- set of wrenches;
- hex key for 17;
- jack;
- balloon key;
- bricks or logs to install a raised front of a car without wheels;
- steering rod puller (if any);
- rust remover (WD-40);
- grease "Litol" or equivalent;
- rag.
Work order:
Conclusion
Upon completion of the assembly work, check how the steering wheel turns, if there is a knock when turning, and what is its play. After that, you can carefully go to the station Maintenance for adjusting the angle of the wheel alignment.

The steering mechanism is one of the key components of any car. On the old samples of the VAZ "Classic", a transverse thrust was installed, and on newer ones - a steering rack. So, in this article, we will consider exactly the modern version, using the example of a VAZ 2114 car.
Design
The steering rack, in its design, resembles a cast metal tube, with a thread applied to it. On the steering column, there is a drive gear that engages with the rack and moves it to the left or right. When driving, the steering rods also move, which are attached at one end to the steering rack in the middle, and at the other to the wheels.
For better contact, the gear is pressed tightly against the rail, due to the metal stop. This emphasis passes through the crankcase, where it is additionally reinforced with a retaining ring.
Causes and symptoms of a malfunction
Since the steering rack is one of those mechanisms that are constantly in motion, it is most prone to various breakdowns and malfunctions. Most often, the following reasons become the cause of the breakdown:
- Wheel impact when hitting a hole at speed. Also, the systematic driving of a VAZ 2114 car, over bumps and bumps, and a sharp rotation of the steering wheel (aggressive driving);
- A sharp change in speed, at the moment the steering wheel is at the extreme left or right point;
- Driving over curbs, bumps, and similar obstacles. This puts a very strong load, and the steering rack may soon fail. Then, the owner of the car will have to spend a lot of money on repairs.
We examined the causes of the breakdown, but how to determine that it is the steering rack that is broken remains in question. Let's look at the main symptoms of a broken rail on the VAZ 2114.
The first, obvious sign is a characteristic noise. If something knocks in front of the car when driving on rough roads, stop driving immediately. If the rack is faulty, noise will be heard in the steering gear area. At the same time, the sensitivity of recoil to the steering wheel is significantly increased.
The reason may be the wear of some parts, such as: rack, hinge, or tie rod. Repair, with this malfunction, is absolutely useless. A complete replacement of worn parts is required. If, however, this signal is ignored, then soon, your VAZ 2114 will simply become uncontrollable, and it is not a fact that this will not happen while driving.
The second sign of a malfunction of the steering rack mechanism is the tight rotation of the front wheels. This happens in two cases: a sharp drop in the power steering fluid level, or its natural development. With the first option, you will most likely need repairs. So, as a sharp leak indicates that the gaskets of the mechanism are worn out and they need to be replaced. To do this, buy a gasket repair kit for the VAZ 2114, and replace all the gaskets with new ones. In the second option, the old fluid just needs to be replaced. Drain the old fluid and refill with new. The problem should be gone.
A more serious problem is if during acceleration the stiff rotation disappears, and instead, something knocks in the wheel area. This indicates that burrs and irregularities appear on the rotor part or on the mating surface. Repair of this part is quite simple, but you do not need to overdo it, as the part can be damaged and it will need to be replaced.
Another symptom of a breakdown of the steering rack on the VAZ 2114 is that the steering wheel does not coincide with the angle of rotation of the wheels. This often happens when the rail is loosened. Repair, in this situation, is simple. Try tightening the tie rod nuts. If this does not help, then the mechanism needs to be replaced.
Buy a repair kit to attach the rack to the tie rod. Replace all nuts and bolts, and also, carefully inspect the attachment points on the parts themselves. If they are loose, repairs will be powerless here, and replacement will be needed.
If the mounting points are normal, try to tighten the nuts as much as possible with bare hands. Next, they should be slightly tightened with a wrench. Try driving over small bumps. If something knocks in the wheel area, stop and try to tighten the nuts more. Repeat the procedure until the knock disappears.
In the case when the rail not only knocks, but also flows, you just need urgent repairs. The reason for this state of the mechanism is worn oil seals. If they are not replaced in time, the liquid will gradually leak out, and the rotation will occur dry. This is fraught with such consequences as: steering failure, right on time.
To carry out the leak elimination procedure, buy a repair kit for a VAZ 2114 or 2115, which includes steering gear oil seals. Disassemble the rack and tie rod mount, and replace the oil seals with new ones. Next, you should tighten and tighten the fastening nuts, and you can check the quality of work. To do this, drive over uneven surfaces, and listen to whether the rake is knocking or not. If there is no noise, stop the car and inspect the mechanism for leaks. If there are no leaks, then you did everything right.
So we sorted out all the possible breakdown options, and how to eliminate them. Now, this problem will not take you by surprise.
The steering mechanism is responsible for the ability to change direction while driving a VAZ 2114 car. This car uses a rack and pinion mechanism.
The principle of operation of this mechanism is reduced to converting the rotation of the gear associated with the drive into the transverse movement of the rack with a gear sector. The movement of this rack is then transmitted by means of steering rods to the suspension struts, which also act as steering knuckles.
These mechanisms have recently become very common due to the simplicity of the design, and are used on many cars. The simplicity of the design ensures proper reliability, however, malfunctions with the steering mechanism are quite common. Some of the malfunctions can be eliminated by replacing worn components, but some malfunctions lead to the fact that the VAZ 2114 steering rack needs to be replaced.
Symptoms
There are not so many signs of a malfunctioning steering mechanism, but each of them can indicate different components with which there are problems. The signs are as follows:
- Increased steering wheel free play;
- The steering mechanism knocks;
- Increasing the effort to rotate the steering wheel;
What can cause a malfunction
Consider each of the signs, as well as what can cause them to appear. It should be pointed out that some problems, such as knocking, may not be related to the mechanism itself.
1. So, the free play on the steering wheel has increased, that is, it dangles more, an increased stroke may additionally appear as a beating in the steering wheel during braking.
This problem may be due to the loosening of the attachment of the ball pins to the stabilizer bar, increased clearance in the ball joints, increased clearance between the rack and pinion.
- If play is found in the steering wheel, the steering ball joints should be examined first. It rarely happens, but it is possible that the nuts securing the tips loosened and the pin began to come out of the seat, due to which a significant gap formed at the attachment point. To fix such a malfunction is simple, just tighten the nuts.
- Wear on the ball ends is much more common, resulting in a gap between the pin and the body. You can fix this problem by changing the tips.
- Backlash in the steering wheel can be formed due to an increase in the gap between the rack and pinion. During the operation of this mechanism, these elements gradually wear out, and the gap between them increases. The repair of this problem boils down to the fact that an adjustment is required, in which it is only necessary to properly tighten the adjusting thrust nut.
2. Knocking in this mechanism can be caused by backlash in the tips, increased clearance between the rack and pinion, as well as loosening of the mechanism itself.
- As for the tips and the gap of the rail, the repair of the mechanism is indicated above, that is, it is enough to tighten the stop nut and that's it.
- Regarding the loosening of the fastening, it is enough just to tighten the clamp nuts that hold the mechanism, and the problem will be solved.
3. Hard rotation of the steering wheel may be due to damage thrust bearing suspension strut (the case when a problem with the suspension affects the steering mechanism), damage to the rack bushing, wedging of the steering tips, wedging of the steering gear bearings.
It should be noted that after repairing many malfunctions, it will be necessary to adjust the position of the wheels (camber-toe angles).
What should be done
All work with the steering mechanism is quite possible to do with your own hands, there is nothing particularly complicated in this. But after work, especially concerning the steering tips, it will be necessary to adjust the toe angles, which are best left to specialists.
If a malfunction occurs, you will first need to diagnose the mechanism to identify the node that caused it. First, the condition of the tips is checked. To do this, they are removed from the support and checked manually. At a serviceable tip, the finger in its body walks with effort, but it should not wedge to some position, such a tip can be put in place and continue to look for faults. If he walks freely and play is felt, then he is replaced.
Next, the gap between the rack and gear is adjusted. For this, a special 6-sided key is used. With it, the stop nut is tightened to the stop, and then loosened by ¼ turn. After that, the nut is fixed by punching. If the adjustment is made correctly, and the condition of the rail is still satisfactory, then the knocks should disappear.
If the adjustment did not help, then most likely the wear of the main components is quite strong and a major overhaul of the mechanism is required with the replacement of the rail, which can also be done by hand.
What is needed for repair
Before proceeding with the repair, a repair kit is purchased. It can be small and include only bushings, seals, anthers, etc. There is also a large repair kit, which also includes a rail. There are a lot of companies producing such repair kits, so which one to choose is up to the owner. But it is still better to choose a manufacturer who is the official supplier of spare parts to the car factory.
To make repairs, it will take not so much:
- Set of spanners;
- Screwdrivers;
- Rags;
- Lubricant;
- repair kit;
How it's done
The sequence of actions is as follows:
After all work, the toe angle must be adjusted.
Work on the restoration of the steering mechanism is not particularly difficult, but some of the operations can cause some inconvenience, but in general, doing everything yourself is quite realistic. The durability of this mechanism in the future will depend on which manufacturer of the repair kit you have chosen.
