Knocking in the steering column: causes of malfunction and solutions

Steering is an important part of anycar. The SDA prohibits the operation of motor vehicles with various breakdowns of the steering system. It is very important to carry out diagnostics or repairs even with minor signs of malfunctions. A knock at the steering column is already quite a serious sign that signals a defect in the steering. Let's consider typical causes of malfunctions and ways of their elimination.knock on the steering column

How the steering column is arranged in the car

Among the main details can be identified mountingsleeve, casing, upper housing. Also in the design there is a body for installing the steering column switches, the ignition key housing, the steering shaft, the contact group and the fasteners. In some models of cars, the design also has a cross, brackets for mounting the steering shaft, and a bearing.

At the base of any steering column is a shaft,located in the casing. Its function is to transfer the rotation of the rudder to the mechanism responsible for turning the wheels. Steering shafts are made of high-quality steels, which means that they have a sufficiently long service life.

Causes of knocking and troubleshooting

Before we look for possible breakdowns,which lead to uncomfortable driving, it is necessary to clearly understand that a knock at the steering column occurs when, for any reason, backlash has formed in the mechanism or the connection density has deteriorated.

Among the main causes of damage to the steering gearthere are several typical. They are the same for most models and brands of modern cars. So, the first reason is an excessively worn or already completely failed bearing in the steering column bracket. Also, the reasons for the knock on the steering column are broken or broken needle bearings in the steering shaft spider. And finally, in the process of car operation, the density of fasteners and connections in the bracket and the cross shafts on the shaft is weakened.

Methods of diagnosis

To understand where the knock on the helmsman came fromcolumn, you can conduct a visual check of each connection - you need to determine the presence of backlashes in the mechanisms. Also during the inspection it is possible to determine faulty bearings.

When checking the status and troubleshootingThe steering gear is tested for each connection in the event that it is weakened. It will also be superfluous after this to test the machine in motion. If in the course of driving the knock on the steering column did not bother, then you can relax. If the driver hears vibrations and knocking, then it is necessary to repair the malfunction.

Any technical element of a modern carlimited to a certain period of service. How long this period will last depends on the loads that are on a particular detail. Special loads in the car undergo suspension, but the steering column experiences not less pressure.reasons for a knock at the steering column

The process of driving on the car is accompanied bya constant rotation of the steering wheel, which means that the steering is extremely vulnerable. When the mechanisms are worn out, the driver hears a characteristic knock at the steering column. "Toyota" is also subject to this problem. It is very important to immediately find the cause and fix the malfunction - otherwise the column may just jam and this will trigger an accident.

What most often fails in the steering columns of cars "Toyota" and VAZ?

Often the first thing that wears out and breaks down is the bushing. This part is erased with time. As a consequence, backlash and knocking appear in the mechanism. It is not difficult to replace the bushing.

The second element, which also often fails, is the lower spider. She is exposed to quite serious loads.

All this is also relevant for VAZ cars, in addition to classic models. Eliminates the knock on the steering column of the VAZ by replacing the same parts.

How to replace the steering column hub on the "Toyota"

To eliminate the knock at the steering column on the"Toyota", you can replace the bushing. The process of replacement will not cause any special difficulties. The first thing they do is remove the stool - it's easy. For this, the bolts are loosened and then the shield is simply removed from the retaining latches. Then a part of the duct is dismantled.

Now that you have access to the steering column,it is necessary to turn away everything that might hinder its removal. When you only need to remove the column, you should mark the marker with the place and position in which it will be necessary to install it after repair. Remove the column carefully, because it has a certain weight. It is recommended to lay the mechanism on something soft - put it with the steering wheel down.

Now we need to start dismantling the bushing, butyou can not do it manually. It is necessary to screw in it two or three screws, which will serve as a support in the process of removal. When the screws are screwed, but not to the end, the steering wheel is covered with something soft, rest against it with legs and pulls the pliers for self-tapping screws. After the application of force, the bushing will come out.

After dismantling, the shaft must be cleaned thoroughly andtreat with a good lubricant. The new bushing is neatly installed in its place. And after that, often a knock goes away. But if the driver still hears it, then it is necessary to replace the crosspiece.

How to replace the lower cross

For repair, unscrew the protective cover,which will prevent you from reaching the cross. To remove it you need to unscrew the three bolts. Before unscrewing the column, it is blocked. This will make it possible to keep the loop of the audio signal intact. Just like in the case of a bushing, you need to make a mark here.

So, here it is - the cross. Now you need to disassemble it - you can use the clamps and carefully cut it. You can install a new one, but first you need to prepare the seats - they are thoroughly cleaned and lubricated.

At the cross the installation site is also betterprepare - before its installation remove the covers and handle all the places with grease. After pressing again check and lubricate the cross - this will save it from moisture.

UAZ "Patriot"

On the cars "Patriot" knock on the steering columnalmost officially was recognized as an incurable problem. But the solution still exists. After the research conducted by the owners of "Patriots" it became clear that the main reason for this trouble is the steering cardan in the engine compartment. It represents two parts, which are connected together by splines. In the lower part there is a through pipe.

Problems with this part are due to its location - it is installed under the coolant reservoir and near the exhaust manifold.

Eliminate the problem of knocking is very simple. Cardan needs to be dismantled and cleaned. Then, carefully separate the two halves of the part and clean them. Slots cardan made of plastic - they are deburred and smeared with silicone grease. You can stop here, but this does not solve the problem completely.

You need a piece 20 cm long from the rubberhoses with a diameter of 18-20 mm. You should also prepare rags. This piece is clogged in the form of a gag in the bottom of the cardan - so you can block the leakage of lubricants. Inside the hose fragment is treated with silicone and put on a problem knot. Then the part is mounted in its place.

As a result of these simple actions, knocking on the steering column at UAZ "Patriot" will pass.
