Front Wheel Bearings

INSPECTION



To check wheel bearing play, raise the vehicle and support it safely. Rock the wheel at 12 and 6 o'clock position. If there is movement, the wheel bearing should be serviced.

To check wheel bearing noise, raise the wheel off the ground, then spin the wheel by hand and let it rotate freely after spinning. Check for wheel bearing noise. If the wheel bearing remains noisy after proper adjustment, replace the wheel bearing.

ADJUSTMENT



Except 850, C70, S70 and V70

The front wheel bearings are not adjustable on the rear drive vehicles. If the lateral run-out on the hub with the disc removed exceeds 0.0012 inch (0.030mm), the hub must be replaced.

REMOVAL & INSTALLATION



Except 850, C70, S70 and V70

See Figures 1, 2 and 3

  1. Raise and support the vehicle safely.
  2.  
  3. Remove the wheel(s).

  5. Remove the brake caliper. Hang the caliper out of the way with a piece of stiff wire. Do not let the caliper hang by the brake hose.
  6.  
  7. Pry off the grease cap.
  8.  
  9. Remove the cotter pin and castle nut.
  10.  
  11. Remove the hub and brake disc assembly. Use a bearing puller to remove the inner bearing if it stays on the spindle.
  12.  

If the vehicle is equipped with separate brake disc and hub, the guide pin and brake disc must be removed from the hub prior to bearing replacement.

  1. Use a brass drift and carefully tap out the grease seal and inner bearing race.
  2.  
  3. Remove the outer bearing race, using a suitable handle and drift.

To install:
  1. Press in a new inner bearing race, using a suitable handle and drift.
  2.  
  3. Press in a new outer bearing race, using a suitable handle and drift.
  4.  
  5. Pack the wheel bearing between the cage and inner race with as much grease as possible. Also smear grease on the outer side of the bearing and bearing races inside the hub. Fill the space in the hub with grease to a diameter of the smallest ball races.
  6.  
  7. On hubs with integrated brake disc, position the inner bearing seal in the hub and press the seal in so the edge lies in the same plane as the hub.
  8.  
  9. On hub with separate hub and brake disc:
    1. Press the sealing ring onto the spindle, making sure that the seal ring is square. The sealing ring lip should face outwards.
