Attention! The condition of the steering significantly affects not only the ease of driving, but also the safety of the vehicle.
The cause of knocking and vibration on the steering wheel may be a faulty condition of the ball joints of the steering rods and steering mechanism, or the wheels of the car. Check the steering according to the procedure described in the subsection "Inspection and testing of the steering system on the car".
Note: A possible cause of vibration and shock on the steering wheel when driving at speeds above 70–80 km/h may be an imbalance in the front wheels. Contact a car service or tire shop to check the front wheel balance. If shocks and vibrations on the steering wheel occur when the brake pedal is pressed, the brake pads must be replaced, and the front brake discs must be repaired or replaced (see "Front wheel brake mechanisms")
