5. Determine necessary quantity of support shims.
A. Lubricate the axle case support bushing with a thin coat of grease and
slide axle case support onto knuckle pin.
B. Position support shims that were removed during disassembly between
axle case support and axle case. Install mounting screws into axle
case. Slowly tighten screws while frequently checking for clearance
(vertical endplay) between axle case support and knuckle pin. If binding
of components is noted before screws are fully tightened, add additional
support shims. Torque screws from 77 to 91 N·m (57 to 67 ft−lb).
C. Use dial indicator to measure vertical endplay of axle case
AXLE CASE ASSEMBLY ENDPLAY: 0.02 to 0.20 mm (0.001 to 0.008 in)
D. Adjust endplay by increasing or reducing number of axle case support
shims.
Note: Axle case support shims are available in 0.1 mm (0.004 in), 0.2 mm
(0.008 in) and 0.4 mm (0.016 in) thickness.
6. After correct support shims have been determined, remove mounting screws,
apply heavy strength thread-locking compound to screw threads, reinstall
screws and torque from 77 to 91 N·m (57 to 67 ft−lb).
Correct engagement between bevel gears is critical to axle
performance and durability.
