Many car owners systematically face the situation in which the steering wheel begins in the braking process. Uncontrolled and intensive vibration or the fighting of the steering column at the moment when the motorist does not expect - the feeling is quite unpleasant. The problem that appeared must be immediately eliminated, in order to avoid emergency and dangerous situations on the road. About this further in the article.
To eliminate the steering wheel, first of all it should be sorted out - what leads to this effect? Many motorists adhere to the opinions that the vibration of the steering wheel when braking appear as a result of poor wheel balancing. Undoubtedly, it may be true, however, the reasons for the biring of the steering wheel are much larger. Therefore, you should not neglect the diagnosis of other nodes, mechanisms and parts when searching for a source of breakage.
The most common causes that cause vibration of the steering column when braking are:
- Wearing wheel fixtures, heating and curvature of nuts and bolts.
- Fault ball support.
- Wear steering rack.
- Fault (defect) of steering tips.
- Faulty or fragmented silent blocks.
- Fault either Bearing Defect.
- Not debatable alignment.
- Deformation of tires.
- Defects and malfunctions of brake discs, often their curvature.
- The brake shoe fault is their production defects or uneven wear.
- Wheel unbalance car.
How to eliminate the cause of the steering vibration
An experienced car owner can independently diagnose the exact cause of the steering wheel batting and remove the detected fault, for which a simple order of action should be adhered to.
inspection of rubber, what problems can be detected
At the first stage, it is necessary to visually inspect the rubber for the presence of defects - it is likely that hernia appeared on it, which can cause a steering vibration.
balancing wheels, how often it needs to be done
The next step is to check the wheel balancing, as well as the presence of the required balancing goods on them. Naturally, one hundred percent guarantee of the lack of unbalance is able to give only a car check on a special stand, but an experienced motorist is able to assess the state of the balance of the wheels. Quite often, balancing solves the problem with the beating of the steering wheel when braking. It is worth noting that the cost of balancing is 70-150 rubles. For one wheel. As for auto-producers, they recommend doing wheel balancing every 15,000 mileage kilometers.
brake pads which problems may be how to eliminate
If the car owner recently mounted new brake pads or some other parts like calipers and disks into brake nodes, it is necessary to dismantle the installed elements, put others, after which the vehicle is tested. It is possible that in the established details there is a factory defect.
brake discs, problems and solutions
If the events did not help detect the problem, go to the next stage - the diagnosis of brake discs, with which such problems may occur: the bands appeared on the surface of the brake disc, and it lost its shine, it means that brake linings were worn out. When braking the car, their wear is able to cause an unpleasant grinding. If the brake linings are worn, it does not rarely open the gum of the guide caliper. Reassemble the situation in this case will help disassemble the node, the lubrication of parts, replacing the rubber band and the subsequent assembly.
deformation of the brake disc, as it affects the battery of the steering wheel, how to eliminate
The disk deformation is also able to cause the steering vibration. The deformed disk looks stitched, ribbed or wavy, in any case - its perfectly round form is lost. Such deformation of the element may cause either strong wear, or overheating with further sharp cooling. In the process of compressing the blocks of the deformed brake disc and there is a beating transmitted by the steering wheel. When deforming or wearing brake discs, their complete replacement is required. In some cases, the grinding and flow of old disks can help, but this is a temporary measure, and as a result, everything will be accurately installed on the installation of new parts.
hub and wheel bearing, effect on steering vibration, how to eliminate
After the disks, check the hub, as well as the wheel bearing. If the inner surface of the bearing is worn, it directly affects the change in the axis of rotation of the hub, and this, in turn, entails the beating of the steering wheel in the process of braking the vehicle.
steering thrust and steering tips, what kind of malfunction is reflected on the rudge of the steering wheel and how to eliminate
If, when checking brake discs, you did not find any deviations and defects, then you need to check the steering thrust. Special attention is paid to the tips - see if there are no gaps in them. To check the steering thrust, slightly lift the car with the help of a jack and pull them on different sides. If during the work you have detected the backlash, you need to replace the steering thrust. It is worth noting that their free move, in addition to the battery, is able to entail a complete loss of car manageability when driving at high speed.
steering rack, malfunction, elimination methods
After the trigger, check the steering rail, since its strong wear is also capable of causeing the battery of the steering wheel. With a substantial worn out of the rail, it will have to repair it to eliminate vibrations when braking.
silent blocks, problems and solutions
After checking the steering rack and steering, it is necessary to inspect the subframe and silent blocks, it is possible that the reason for the steering wheel vibration lies in them. There is no clear algorithm for checking these elements, each motorist checks their condition in its own way. When silent blocks are detected, it is necessary to replace them with new ones.
ball supports how to check with your own hands and troubleshoot
If there are no malfunctions and defects in the steering rail and steering rods, check the condition of the ball supports - the ball support raised by the car's jack is placed on a flat steady surface in such a way that the wheel hanging in the air freely. Next you need to take up the bottom and top of the wheels and try to show it, pulling on yourself. If the ball support is risen, it means it was significantly worn out and requires replacement.
mounting wheel
The last step is to check the fasteners of the wheels, as well as the state of nuts and bolts. Weak fasteners do not rarely cause steering. If you find this problem, it is quite simple to remove, tightening the fasteners nuts.
Profi Council, what to do if the defect is not detected by the defect
As a rule, the actions listed above are enough to detect the cause of the vehicle steering in the braking process, as well as to further eliminate it. If the car owner does not have enough experience or the reason is so not obvious that the diagnostic has not sufficiently for its detection, it is necessary to resort to the help of professionals.
