Assembling the Wheel Hubs and Bearings
Chassis: Service and Repairs
Refer to Figure 48 for the following procedure.
1. Assemble the wheel hub as follows:
A. If the lug screws were removed from the wheel hub, press the lug screws
fully into the hub. Ensure that the lug screw flange is pressed fully to
the hub surface.
B. If the bearing cups were removed from the wheel hub, press the inner
and outer cups into the wheel hub until they seat against the wheel hub
shoulder.
C. Fill the wheel hub approximately 50% full of grease.
D. Pack both bearing cones with grease. Install greased inner bearing cone
into the cup on inboard side of the wheel hub.
The oil seal should be pressed in so that it is flush with the end
of the wheel hub. The lip of the oil seal must be toward the inner
bearing.
E. Lubricate the inside of new oil seal and press it into the wheel hub.
Note: Ensure that you do not damage the oil seal in the wheel hub.
2. Install the wheel hub onto the axle spindle.
3. Install greased outer bearing cone, spindle washer, and nut onto the spindle
shaft.
4. While rotating the wheel hub by hand, torque the nut to 8.5 to 20.3 N∙m (75
to 180 in-lb) to seat bearings. Loosen the nut until it is away from the spindle
washer and the wheel hub has end-play. Finally, while rotating the wheel
hub, tighten the nut to 1.7 to 2.3 N∙m (15 to 20 in-lb).
5. Install the nut retainer and a new cotter pin to secure the nut. Install the
dust cap.
