5. Determine necessary quantity of support shims.<br />
A. Lubricate the axle case support bushing with a<br />
thin coat of grease and slide axle case support onto<br />
knuckle pin.<br />

57 to 67 ft -lb<br />
(77to91N-m)<br />
B. Position support shims that were removed during<br />
disassembly between axle case support and axle<br />
case. Install mounting screws into axle case. Slowly<br />
tighten screws while frequently checking for clearance<br />
(vertical endplay) between axle case support<br />
and knuckle pin. If binding of components is noted<br />
before screws are fully tightened, add additional support<br />
shims. Torque screws from 57 to 67 ft -lb (77 to<br />
91 N -m).<br />
C. Use dial indicator to measure vertical endplay of<br />
axle case (Fig. 22).<br />
AXLE CASE ASSEMBLY ENDPLAY:<br />
0.001 to 0.008 in. (0.02 to 0.20 mm)<br />
D. Adjust endplay by increasing or reducing number<br />
of axle case support shims.<br />
NOTE: Axle case support shims are available in<br />
0.004 in. (0.1 mm), 0.008 in. (0.2 mm) and 0.016 in.<br />
(0.4 mm) thickness.<br />
6. After correct support shims have been determined,<br />
remove mounting screws, apply heavy strength thread--<br />
locking compound to screw threads, reinstall screws<br />
and torque from 57 to 67 ft -lb (77 to 91 N -m).<br />
IMPORTANT: Correct engagement between bevel<br />
gears is critical to axle performance and durability.<br />

7. Temporarily install the bevel gear case/axle case assembly<br />
on the axle support. Position a dial indicator at<br />
the tooths center. Prevent the axle from turning and<br />
measure the upper bevel gear to differential shaft gear<br />
backlash (Fig. 23).<br />

8. Adjust backlash by increasing or reducing axle bearing<br />
shim thickness (see Differential Shafts in this section<br />
of this manual).<br />
NOTE: Axle bearing shims are available in 0.004 in.<br />
(0.1 mm), 0.008 in. (0.2 mm) and 0.020 in. (0.5 mm)<br />
