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 clear- ance (vertical endplay) between axle case support and knuckle pin. If binding of components is noted before screws are fully tightened, add additional sup- port shims. Torque screws from 57 to 67 ft--lb (77 to 91 N--m).

C.Use dial indicator to measure vertical endplay of axle case (Fig. 22).

AXLE CASE ASSEMBLY ENDPLAY: 0.001 to 0.008 in. (0.02 to 0.20 mm)

D.Adjust endplay by increasing or reducing number of axle case support shims.

NOTE: Axle case support shims are available in 0.004 in. (0.1 mm), 0.008 in. (0.2 mm) and 0.016 in. (0.4 mm) 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 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 bevel gear 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. 23).

UPPER BEVEL GEAR BACKLASH: 0.004 to 0.016 in. (0.10 to 0.40 mm)

8.Adjust backlash by increasing or reducing axle bear- ing shim thickness (see Differential Shafts in this section of this manual).

NOTE: Axle bearing shims are available in 0.004 in. (0.1 mm), 0.008 in. (0.2 mm) and 0.020 in. (0.5 mm) thickness.
