Technical characteristics



Check of a backlash of the wheel bearing

Wheels rotate ahead and behind on двухрядных ball-bearings. Behind in models with a forward drive radially-persistent ball-bearings are established. In quattro the same ball-bearings that ahead. With greasing of long action they usually maintain the run considerably exceeding 100 000 km.

 PERFORMANCE ORDER

  1. Serially strong undertake the top part of the wheels reliably standing on the earth, and try to move them in a cross-section plane to the car.
  2. At faultless bearings practically will not be люфта.
  3. If the backlash let your assistant will strongly press a pedal of a brake is felt and once again shake a wheel: if the backlash is not present more, the reason only in the wheel bearing.
  4. If, despite it, there is a backlash it is necessary to check up a wheel suspension bracket.
  5. Defective wheel bearings draw to themselves attention noise at work. What bearing is damaged, is better to check up on the lifted car. The wheel with the defective bearing draws to itself attention rough noise at work.

 Council: Back wheel bearings in models with a forward drive can be regulated. It cannot be made with back wheel bearings in models quattro, and also with all forward wheel bearings.
