Wheel Bearings

Print

GENERAL RECOMMENDATIONS



The front wheel bearings should be checked when replacing brake pads or removing the brake disc for any service. They should be repacked every 22,500 miles regardless of any other required service. Rear wheel bearings require no attention. The front wheel bearings should be removed, cleaned, and packed with a grease recommended for disc brake service.

  1. Raise the front wheel off the floor.

  4.  
  5. Remove the cotter pin and the nut lock.
  6.  
  7. While turning the wheel, tighten the nut to 240-300 in. lbs.
  8.  
  9. Back the adjusting nut off completely, then tighten it finger-tight. Install the nut lock and the cotter pin.
  10.  
  11. Coat the inside of the cap with grease (don't fill it) and replace the cap.

Correct adjustment should result in 0.001-0.003 in. end-play.

REMOVAL, PACKING, & INSTALLATION



  1. Raise and support the car. Remove the wheel.
  2.  
  3. Remove the caliper.
  4.  
  5. Remove the disc and the outer bearing.
  6.  
  7. Remove the inner bearing.
  8.  
  9. To remove the bearing cone if necessary, drive the inner seal out of the hub and drive the cone out with a 3 / 4 in. diameter non-metallic rod. Install the new cone and install the new seal with the lip inward.
  10.  
  11. Clean the bearings thoroughly in a safe solvent. Check their condition, but don't spin them any more than is absolutely necessary.
  12.  
  13. Clean the spindle and apply a light coat of grease on all polished surfaces.
  14.  
  15. Pack both wheel bearings using wheel bearing grease made for disc brakes. Ordinary grease will melt and ooze out, ruining the pads. Place a healthy glob of grease in the palm of one hand and force the edge of the bearing into it so that the grease fills the bearing. Do this until the whole bearing is packed. Grease packing tools are available to make this job a lot less messy.
  16.  
  17. Fill the hub grease cavity with grease even with the inner diameter of the bearing cups. Replace the hub and adjust the bearings.
  18.  
  19. Replace the caliper.
  20.  
  21. Replace the wheel.
