Check backlash the bearing of a nave of a wheel

Forward wheels движутся on двухрядных ball-bearings. Behind on front-wheel models radially-persistent conic roller bearings are established. On all-wheel drive cars behind there are same ball-bearings, as well as in front. They установленны on консистентную greasing and usually serve much longer 100 000 km. Defective bearings attract attention noise at movement. If noise becomes louder, for example on the right turns, means, the left bearing of a nave of a wheel is faulty.


  1. Try to turn one behind another wheels firmly standing on the earth concerning their vertical axis.
  2. At serviceable bearings should not be almost any backlash.
  3. If люфт it is notable, ask the assistant to press strongly a pedal of a brake and once again shake a wheel: if it is not felt any more backlash, means, the reason only in the bearing.
  4. If still is available люфт: it is necessary to check up a wheel suspension bracket.
  5. Now it is necessary to lift the car and to turn a wheel: if it moves hard or jerky, means, the bearing is established too hardly. If you distinctly hear a gnash, it is necessary to replace the bearing.

 The help: back bearings of naves of wheels of front-wheel models can be regulated. Back bearings of all-wheel drive models, and also bearings of all forward wheels are not regulated.
