Wheel Bearing Adjustment
Stamped Locking Nut System
Proper wheel bearing adjustment maximizes wheel bearing
and seal life. Proper adjustment can also extend brake lining
life by preventing lining contamination caused by seal leaks.
1. Inspect the spindle threads and spindle nut for cor-
rosion and clean thoroughly or replace as required.
2. Pre-lubricate all bearings.
3. Install the inner bearing in to the hub and install the
wheel seal.
4. If grease lubricant is used, fill the hub cavity with the
appropriate lubricant.
5. Install the hub on the spindle with care, to prevent
damage or distortion to the wheel seal.
Never mix grease and oil lubricants.
6. Install the outer bearing on the spindle.
7. Install the retaining washer and adjusting nut.
8. Seat the bearing by tightening the adjusting nut to
100 lbs. ft. (135 N•m).
9. Loosen the adjusting nut one-half turn.
10. Re-tighten the adjusting nut to 50 lbs. ft. (68 N•m)
while rotating the hub.
11. Back off the adjusting nut 1/8 turn.
12. Install the stamped locking nut.
Never tighten the adjusting nut to align the cotter pin slot.
This can pre-load the bearings and cause a premature bear-
ing failure.
13. Verify that the wheel end play is between .001" and
.005" (.025 and .125mm) using a dial indicator. If
reading does not fall within the range, repeat this
procedure.
14. Install the cotter pin and bend legs around the
stamped locking nut.
15. Attach the hub cap.
16. If oil lubricant is used, fill the hub cap cavity with the
appropriate lube. Install oil fill plug and tighten to
specified torque.
