Knocking in the steering rack: how to remove?

For many car enthusiasts, one of the problems in the process of operating a vehicle is a knock on the steering rack, which occurs over a certain time. The problem does not arise because of poor quality construction. On the contrary, it in itself is very reliable, but only the operation of the vehicle improperly provokes the appearance of this kind of malfunction. In addition, the low quality of domestic roads will render any tested mechanism useless even with high reliability.

The malfunction, which directly affects the steering rack, manifests itself in the form of knocking or creaking when operating the car. Appearing knocks in the steering rack can not only adversely affect the behavior of the car on the road, but also lead to an accident. Therefore, in this article we will consider not only how to eliminate the knocking of the steering rack, but also the causes of the malfunction. Also for motorists, we will provide a chapter in which methods for increasing the service life of the helmsman will be described.

Principle of operation of the mechanism

The rack control consists of the following components:

• rack;
• gear;
• Steering shaft;
• The steering mechanism;
• Tips.

The principle of operation of this unit is the following: when the steering wheel is rotated to the pinion from the steering shaft, a force is transmitted. It, as a result, sets in motion the steering rack. The task of the rack is to convert the rotational motion into the translational motion.

Causes of malfunction

Having considered the basic principle of the device, to understand the reasons why there is a knock on the steering rack is not so difficult. Most often, the causes of the malfunction may be:

1. Formation of backlash in the places of engagement of steering elements. This is primarily due to the construction unsuitable for local roads, which simply does not withstand heavy loads, as well as with constant driving on the road off-road.
2. As a result of wear of the parts, mud deposits fall into the interior, which leads to corrosion. The resulting rust reduces the quality of the engagement to a minimum, and knocks begin to appear during movement.

Preventive actions

To exclude the full occurrence of knocks in the steering rack is quite difficult, but it is possible (if you follow simple rules). Among the main preventive measures are:

• Complete disregard of sudden braking and starts (of course, if there is no risk of an accident), as aggressive maneuvers greatly wear out the steering mechanisms.
• It is not necessary to use the curb as a cut-off during parking, because minor impacts by the wheel on it will later sound very deplorable.
• The same applies to the impact on the curb and similar difficult to overcome obstacles.
• Overcoming uneven roads in the form of pits, potholes, lying policemen, should be carried out at minimum speeds. Do not follow the rule: "more speed - less bumps". Any hummock at speed is the strongest blow to the helmsman.
• Continuous monitoring of the condition of oil seals and anthers on the steering mechanisms.
• Diagnosis of the appearance of the slightest signs of a malfunction.

Simple repair technique

On the question of how to remove the knock of the steering rack on any of the machines, the answer is quite simple: you need to pull the adjusting screw. This action, of course, will help for some time to move on the vehicle without any problems. But sometimes a strong tightening of the screw leads to a violation in the control, namely, the steering response deteriorates. When cornering, turn the steering wheel in the right direction, it will be very difficult, and as a result, there will be discomfort from driving and great fatigue.

Effective way to eliminate knocking

To remove the knocking in the steering rack, it is enough to remove the shaft. Dismantling is carried out in accordance with what node is installed on the car. There may be a simple rack-and-pinion mechanism or a unit with a power steering.

If the mechanism of the first type, it is enough to unscrew the fastenings of the steering tips, and then remove the gear. If the car has a power steering, it is necessary to pre-drain the fluid and unscrew the high-pressure pipes. It is worth noting that self-repair with an amplifier is quite complicated and requires the experience of similar works and the availability of an assistant.

After dismantling, the shaft must be punctured. From it, remove traces of corrosion or production. Damaged items are restored and processed with a thin layer of chromium. Then all the elements are thoroughly polished.

These works are highly accurate, which makes it possible to extend the life of the steering rack. If in the mechanism corrosion of a support rack is observed, then the complete replacement of the part is indispensable. In any case, you can get rid of the problem, but you must perform an initial diagnosis to determine the complexity of the repair.

Repair of the steering "Lada Kaliny"

The knocking of the steering rack "Kalina", like any other model of the domestic car factory, can demonstrate during operation on uneven surfaces. In addition, when driving, blows to the steering wheel are transmitted. Before doing repairs, you need to understand why the steering rack is audible. "Lada Kalina" knock can be made because of the loose adjusting screw or heavy wear and misuse of the car.

For adjustment, you need keys 10 and 13, as well as a puller for the helmsman. For this, there is no need to drive the car to a pit or to a ski lift. All operations are carried out directly in the engine compartment.

To adjust the rail, you need to remove the battery, since its location interferes with ongoing work. With the help of a key for 10 terminals are removed, and the "cloak" on 13 turns off the battery holder.

After removing the battery, it is necessary to dismantle the stand under it, which is fixed to 4 bolts. This will give you full access to the steering rack. On the lower side of the housing is an adjusting bolt with an inner plastic cap, which must also be removed. After these procedures with the help of a special switch you need to tighten the traction.

Adjustment Features

On a note! It is not necessary to tighten the adjusting bolt very much, because during the movement, when turning, there can be a dangerous phenomenon - snacking.

To adjust it is necessary so: to turn a bolt by a maximum on 20 degrees then it is necessary to sweep and check up, whether the knock of the steering rack of "Lada Kaliny" has disappeared. If the vibration remains, you can tighten the bolt once more, but a maximum of 15 degrees.

However, if the re-pulling has not yielded any results, it is necessary to overhaul the steering rack. In this case, the steering tips, glands, anthers are replaced.

Troubleshooting on Toyota

Despite the Japanese quality, knocking in the steering rack "Toyota Corolla" publishes often. And motorists have to solve this problem. In Russia, the cars are very popular. Car enthusiasts now and then have to decide how to remove the knock of the steering rack. "Toyota Corolla" interests them the most. Previously, remove this problem was very difficult, but thanks to the masters there was a way out.

It is necessary to buy a grease nipple for 6 or 8, a high-quality lubricant and be patient with work. Doing work is best in the garage on the pit.

Further, in order to eliminate the knocking of the steering rack, "Toyota Corolla" is placed on a flat surface. Armed with a drill of the correct diameter and drill, it is necessary to drill a hole in the rack so that it is convenient not only to turn the grease nipple, but also to make the rack packing with grease using a syringe.

The thread under the grease nipple is cut using a tap. After this, it is necessary to use a special sealant, which is suitable only for threaded connections. As soon as it is applied, it is necessary to screw the grease nipple into the hole and make the grease packing in the rail.

To completely remove the knocks, one cylinder of 400 ml is needed. It is worth remembering that after the syringe, you need to remove excess lubricant and close the oil can with a plastic cap.

Use only the lubricant that is suitable for the Toyota car rails. In such a simple way, you can eliminate the knock in the steering rack (Toyota Tundra, including).

In other cases, these cars are hit by a steering gear or a pipe that is responsible for adjusting the rudder in height. The mechanism must be diagnosed with the existing backlash.

How to eliminate the knocking of the Lacetti steering rack

On cars "Chevrolet Lachetti" this malfunction appears because of the unusable steering tips, the replacement of which will cost the owner much cheaper than the rake. In this case, all the work can be done independently.

The replacement of two tips will take a little over half an hour. However, this will save money and make sure the quality of the work performed. To replace the tips on the "Lacetti" you will need two "capes" for 19 and 22, a balloon key, a jack. In addition, the knocking of the steering rack ("Lacetti" 1.6 SE is not an exception) is due to out of order pillars or stabilizer bushings.

Thus, it is quite easy to eliminate the mentioned fault. Most often, you can do it yourself, without spending extra money for special workshops. However, before you remove the knocking of the steering rack, you need to make a thorough diagnosis of the system.
