REASSEMBLY
1. Pack wheel bearings with a premium, water
resistant, high speed wheel bearing grease.
2. Apply a light coat of grease on the bearing races.
Recommended Wheel Bearing Lubrication
Specifications are as follows:
3. Install inner wheel bearing in hub.
4. Install new grease seal in hub using a small
hammer or proper seal installation tool.
5. Install hub on spindle.
6. Install outer wheel bearing onto the spindle.
7. Install bearing retaining washer and spindle nut.
8. Tighten spindle nut to 50 ft/lbs (68 Nm).
9. Loosen nut to remove the torque. Do not rotate
the hub
10. Finger tighten until just snug.
11. Install and secure cotter pin or nut locking tab.
12. Install wheel bearing grease cap.
13. Install tire and rim assembly.
14. Tighten lug nut using a cross tightening
sequence to 15 to 20 ft/lbs (20 to 27 Nm).
Use an anti-seize compound on the threads of
the lug studs. This will prevent galling and seizure
of the lug nut to the stud.
15. Final torque lug nuts to 80 to 90 ft/lbs (110 to 125
Nm).
16. Remove jack stands and lower wheel to ground.
Re-torquing of lug nuts is required after initial 50
miles (80 km) of travel and then again after 200
miles (320 km) of travel. Failure to ensure proper
lug nut torque may result in tire, wheel or hub
failure that will cause damage to MMP4 and tow
vehicle.
