Front Wheel Bearings

Print

Once every 30,000 miles, clean and repack wheel bearings with a wheel bearing packer. Remove any excess grease from the exposed surface of the hub and seal.

REMOVAL, REPACKING, INSTALLATION AND ADJUSTMENT



See Figures 1 through 14


WARNING
It is important that wheel bearings be properly adjusted after installation. Improperly adjusted wheel bearings can cause steering instability, front end shimmy and wander, and increased tire wear.

  1. Raise the car and support it at the lower arm. Remove the tire and wheel assembly.
  2.  
  3. Remove the brake caliper and support it on a wire.
  4.  
  5. Remove the dust cap, cotter pin, castle nut, thrust washer and outside wheel bearing.
  6.  
  7. Pull the disc/hub assembly from the steering knuckle.
  8.  
  9. Pry out the inner seal and remove the inner bearing.
  10.  
  11. Wipe out the grease from inside the hub.
  12.  
  13. Clean the wheel bearings thoroughly with solvent and check their condition before installation. After cleaning, check parts for excessive wear and replace damaged parts.
  14.  


WARNING
Do not allow the bearing to spin when blowing dry with compressed air, as this would allow the bearing to turn without lubrication.

  1. Apply a sizable amount of lubricant to the palm of one hand. Using your other hand, work the bearing into the lubricant so that the grease is pushed through the rollers and out the other side. Keep rotating the bearing while continuing to push the lubricant through it.
  2.  
  3. Apply grease to the inside of the hub and install the inner bearing in the hub. Install a new grease seal, be careful not to damage the seal.
  4.  
  5. Install the disc/hub assembly onto the steering knuckle. Install the outer bearing, thrust washer and castle nut. Torque the nut to 12 ft. lbs. (16 Nm) while turning the wheel.
  6.  
  7. Back the nut off and retighten it by hand until nearest slot aligns with the cotter pin hole.
  8.  
  9. Insert a new cotter pin.
  10.  
  11. Mount a dial indicator onto the vehicle so that any end-play in the hub can be measured. Measure the end-play and record the value. End-play should be between 0.001-0.005 in. (0.025-0.127mm). If play exceeds this tolerance, the wheel bearings should be replaced.
