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. Positionsupport shims thatwere removed during
disassembly between axle case support and axle
case. Install mounting screws into axle case. Slowly
tighten screws while frequently checking for clear-
ance (vertical endplay) between axle case support
and knuckle pin. If binding of components is noted
beforescrewsarefully tightened,addadditionalsup-
port shims. Torque screws from 57 to 67ft--lb (77 to
91 N--m).
C. Use dial indicator to measure vertical endplay of
axle case (Fig. 20).
AXLE CASE ASSEMBLY ENDPLAY:
0.001 to 0.008 inch (0.02 to 0.20 mm)
D. Adjustendplay by increasingor reducing number
of axle case support shims.
NOTE: Axle case support shims are available in
0.004 inch (0.1 mm), 0.008 inch (0.2 mm) and 0.016
inch (0.4 mm) thickness.
6. After correct support shims have been determined,
removemounting screws, applyheavy strengththread--
locking compound to screw threads, reinstall screws
and torque from 57 to 67 ft--lb (77 to 91 N--m).
IMPORTANT: Correct engagement between bevel
gears is critical to axle performance and durability.
7. Temporarily install the bevelgear case/axle case as-
sembly on the axle support. Position a dial indicator at
the tooths center. Prevent the axle from turning and
measure the upper bevel gear to differential shaft gear
backlash (Fig. 21).
UPPER BEVEL GEAR BACKLASH:
0.004 to 0.016 inch (0.10 to 0.40 mm)
8. Adjustbacklash by increasing orreducing axle bear-
ingshim thickness(seeD ifferentialShafts inthissection
of this manual).
NOTE: Axle bearing shims are available in 0.004 inch
(0.1 mm), 0.008 inch (0.2 mm) and 0.020 inch (0.5 mm)
thickness.
