Installation (Fig. 10)
1. If brake rotor was removed from wheel hub, place ro-
tor on hub and secure with four (4) socket head screws.
Torque screws from 9 to 11 ft- -lb (13 to 14 N- -m).
2. If any wheel studs were removed from wheel hub,
use a press to install new studs into hub (Fig. 11). Make
sure that stud shoulder is fully pressed against housing
surface.
3. If bearing cups were removed from the wheel hub,
press new cups into the hub until they seat against the
shoulder of the hub (Fig. 11).
NOTE: Use High Temperature Mobil XHP--222 grease
(or equivalent) when greasing front wheel hub compo-
nents.
IMPORTANT: The lip of the oil seal must be toward
the bearing. The seal should be pressed in so it is
flush with the end of the wheel hub.
4. Pack both bearings with grease. Install one bearing
into the bearing cup on inboard side of the wheel hub.
Lubricate the inside of a new oil seal and press it into the
wheel hub with the seal lip toward the bearing.
5. Fill wheel hub cavity between bearings approximate-
ly 50% full of grease. Position remaining bearing into the
outer bearing cup.
6. Slide the wheel hub assembly onto the spindle shaft
and secure it in place with the tab washer and jam nut.
DO NOT fully tighten the nut.
7. While rotating the wheel hub by hand, torque the jam
nut to 130 in-lb (14.7 N--m) to set the bearings. Then,
