3.
Remove hub cap, cotter pin, set cover and nut.
4.
Remove hub and plate, being careful not to drop washer and bearing.
5.
Remove dust cover.
6.
Remove cotter pin and tie rod end nut, then, using tool 490118850C or equivalent, separate tie rod end from knuckle. If removal is difficult,
lightly tap ball joint coupling of knuckle with a hammer.
7.
Remove knuckle to ball joint attaching bolt, then push lower arm downward to separate knuckle and ball joint.
8.
Remove shock absorber to knuckle attaching bolts.
Disassembly
1.
Scribe alignment marks on disc plate and wheel hub, then remove setscrews.
2.
Install lug nuts and tap lug nuts with copper hammer to remove hub.
3.
Remove oil seal and bearing.
4.
Remove sensor rotor, if equipped.
Inspection
1.
Check bearings for wear damage or seizure, replacing as necessary. If replacement is necessary, replace inner bearing, outer bearing and
front hub as an assembly.
2.
Check hub for cracking or damage, replacing as necessary.
3.
Check knuckle spindle for cracking or damage and the oil seal friction surface for damage or rust, replacing as necessary.
4.
Check knuckle and knuckle arm for damage, replacing as necessary.
5.
Check dust cover and hub cap for deformation, replacing as necessary.
Assembly
1.
Pack bearing cone and roller assemblies with lithium base grease.

Install dust cover, then the hub and plate, and adjust bearing preload as follows:
a. Torque nut to 14-22 ft.lbs., then turn hub and plate two or three times to seat bearing.
b. Loosen nut until it can be turned by hand.
c. Attach a pull scale to wheel lug bolt and measure frictional force.
d. Tighten locknut until reading is .9-2.2 lbs., then insert set cover and secure with new cotter pin.
8.
Install speed sensor, if equipped, and check clearance between sensor rotor and speed sensor. Clearance should be .016-.39 inch (.4-1 mm).
