4. If removed, install brake disc on front hub, tightening attaching bolts alternately and evenly to 36-44 ft. lbs. After assembling, check brake disc
runout. Brake disc runout should not exceed 0.006 inch.
5. Carefully install front hub on steering knuckle spindle.
6. Install outer bearing on spindle, then install spindle nut.
7. Adjust wheel bearings as follows:
a. Torque bearing locknut to 94-145 ft. lbs. while rotating hub to seat bearings.
b. Loosen spindle nut and retighten to 18 ft. lbs., then back off 30°.
c. Install lock washer. If hole in lock washer is not aligned with hole in spindle nut, the nut may be loosened up to an additional 20° to obtain
proper alignment.
d. Using a suitable spring scale or torque wrench, measure force required to rotate front hub.
e. The force required to rotate the front hub assembly should be 1.1-4.0 lbs. (spring scale) or 3-11 inch lbs. (torque wrench), and endplay should
be less than 0.002 inch. If rotating force is not within specifications, repeat adjustment.
f.
When adjustment is correct, secure washer with retaining screws.
8. On models with automatic locking hubs, measure brake contact surface depth as follows:
Fig. 15 Measuring brake contact surface depth. Automatic locking hub
a. Measure dimension A, in two places using suitable depth gauge.
b. Average of two readings should be 0.46-0.48 inch. If depth is greater than specified, install suitable shims. If depth is less than specified,
recheck hub and bearing installation.
9. Apply grease to inner surface of free wheeling hub body assembly.
10. Apply semi-dry sealant to front hub surface to which the free wheeling hub body assembly is attached.
11. Align tab on free wheel hub with groove on spindle, install free wheeling hub body assembly on front hub, then torque attaching bolts to 37-43 ft.
lbs.
12. Reverse remaining procedure to complete installation.
