EXCERPT:
Wheel Bearing Adjustment
FINAL DRIVE
1. Retainer nut. 2. Wheel. 3. Bearings. 4. Wheel stud.
1. Put an 8.00 in. (203.2 mm) torque wrench on wheel stud (4).
2. Tighten nut (1) while turning wheel (2) to a torque of 160 ± 50 lb. in. (184.5 ± 57.7 cm.kg). This torque reading must be held through one complete revolution of wheel (2). If necessary, do the procedure again to get the correct torque.
3. After getting the correct preload on bearings (3), loosen nut (1). Again, tighten nut (1) while turning wheel (2) to a torque of 75 ± 25 lb. in. (86.5 ± 28.8 cm.kg) for one complete revolution.
4. Turn the nut to the next groove and lock in place.
