Check of a side play of the wheel bearing

Forward wheels move on two-row ball-bearings. Behind on front-wheel models radial-stop conic roller bearings are installed. On all-wheel drive cars behind there are same ball-bearings, as well as in front. They are established on jellied lubricant and usually 100 000 km serve much longer. Defective bearings attract attention noise at the movement. If noise becomes louder, for example on the right turns, so the left wheel bearing is faulty.

 PERFORMANCE ORDER

  1. Try to turn one behind another the wheels which are firmly standing on the earth concerning their vertical axis.
  2. At serviceable bearings there should be no side play.
  3. If the side play is notable, ask the assistant to press strongly a pedal of a brake and once again shake a wheel: if any more the side play, so the reason only in the bearing is not felt.
  4. If still there is a side play: it is necessary to check a wheel suspension bracket.
  5. Now it is necessary to lift the car and to turn a wheel: if it moves hard or breakthroughs, so the bearing is installed too hardly. If you distinctly hear a gnash, it is necessary to replace the bearing.

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