The car shall not produce any extraneous sound in the car. The movement may indicate: Mechanical injuries. For example, the wheel may turn on the coverings due to the undercover deformation or the suspension elements. For example, the joints of equal angular velocity (STIs) or bearing pin. The wheel may turn silently on a flat road, but on uneven conditions, waves, or at turns, the wheel may turn on the arches and wings, making a characteristic cross. This is because the automatic transmission of the automatic gearbox to the D position on the wheels starts the torque and the vehicle remains stationary only because of the brakes. When the brake pedal is released, the brake pedal is three times the brake disc which causes the brakes to be crossed. This is not a malfunction, and the volume of the scratchpad depends only on the composition and wear of brake pads and discs.
- Mechanical injuries. For example, the wheel may turn on the undercovers due to the deformation of the cover or suspension elements.
- The wear of the parts of the running gear. For example, the joints of equal angular velocity (SUSPUS) or bearings of the step.
- Cags trapped in suspension elements or braking system: the most common case is the stoning between the brake disc and the casing of the brake disc.
- Sometimes, the reason for the staples may be wheel discs or tyres of inappropriate size. The wheel can turn silently on a flat road, but on uneven conditions, waves, or turns, the wheel may turn on the arches and wings, making a characteristic cross.
- The movement is often used for vehicles with automatic gearbox. This is because the automatic transmission of the automatic gearbox to the D position on the wheels starts the torque and the vehicle remains stationary only because of the brakes. When the brake pedal is released, the brake pedal is three times the brake disc which causes the brakes to be crossed. This is not a malfunction, and the volume of the scratchpad depends only on the composition and wear of brake pads and discs.
When the crossing is made, it is necessary to diagnose the running gear, as the crossing may indicate a serious malfunction that may cause an accident.
