Wheel Bearings



The wheel bearings are not adjustable. If a wheel bearing is out of specifications, it must be replaced. Using a dial indicator, check for looseness. If play exceeds 0.005 inch (0.127mm), the bearing wear is excessive and the hub/bearing should be replaced.

    Insert a drift punch through the caliper and into the rotor cooling fins to prevent the rotor from turning.

  3. Apply a light coating of grease to the steering knuckle bore.
  5. Slide the hub assembly onto the halfshaft as far as possible. If the hub will not bottom out on the halfshaft, install the hub mounting bolts and use the halfshaft nut to draw the hub onto the halfshaft.
  7. Once the hub is flush with the steering knuckle, remove the mounting bolts and install the dust shield.

  11. Install the mounting bolts. Torque the bolts to 70 ft. lbs. (95 Nm).
  13. Place the transaxle in N .
