Wheel Hub (Locking): Service and Repair

NOTES:
- To prevent damage to the spindle during removal, remove adjusting nut locking key from spindle keyway under adjusting nut prior to nut removal.
- A slight movement of the nut will loosen the locking key so that a magnet can be used for removal.
- During the front wheel bearing adjustment procedure, align the closest two holes in the wheel bearing adjusting nut with the center of the spindle keyway slot.
- Advance the nut to the next hole if required. To ensure proper wheel retention, install adjusting nut locking key in alignment with spindle keyway and insert into locknut holes.
- The double humped portion must be completely seated and flush with the locknut assembly.
