- Remove the axle shaft spacer, needle thrust bearing and the bearing spacer. Remove the outer wheel bearing lock nut from the spindle using Four-Prong Spindle Nut Spanner Wrench (T83T-1197-A). Ensure the tabs on the wrench engage the slots in the lock nut.

- Tighten the inner lock nut to 35 ft. lbs. (47 N.m) to seat the bearings. Spin the rotor and back-off the inner lock nut 1/4 turn. Install the lock washer on the spindle. It may be necessary to turn the inner lock nut so the pin on the lock nut aligns with the closest hole in the lock washer.
