threadlocker and tighten the knuckle pin mounting screws to 23 to 27 N·m
(17 to 20 ft-lb).
5. Determine necessary quantity of the support shims.
A. Lubricate the axle case support bushing with a thin coat of grease and
slide the axle case support onto the knuckle pin.
B. Position the support shims that were removed during disassembly
between the axle case support and the axle case. Install the mounting
screws into the axle case. Slowly tighten the screws while frequently
checking for clearance (vertical end-play) between the axle case support
and the knuckle pin. If binding of components is noted before the screws
are fully tightened, add additional support shims. Torque the screws to 77
to 91 N·m (57 to 67 ft-lb).
