Fig. 45 Drive Pinion Turning Torque Specifications (W/Oil Seal Installed)
4. Adjust drive pinion preload as follows:
a. Fit drive pinion front shims between drive pinion spacer and drive pinion front bearing inner race.
b. Torque companion flange to 116-159 lb-ft, using end yoke holder tool No. MB990767 or equivalent.
NOTE: Do not install oil seal.
c. Using a torque wrench, measure drive pinion turning torque as shown.
d. Compare measurement to specification. If turning torque is not within specification, adjust by replacing drive pinion front shims or drive
pinion spacer.
NOTE: If a number of shims will be required to bring preload within specified value, reduce the number of shims by replacing the spacer.
e. Remove companion flange and drive pinion, then drive oil seal into gear carrier front lip. Apply a thin coat of multipurpose grease to the oil
seal lip.
f.
Apply a thin coat of multipurpose grease to companion flange washer contacting surface prior to installing drive pinion.
g. Install drive pinion assembly and companion flange with mating marks aligned, and torque companion flange self-locking nut to 116-159 lb-ft.
h. Measure drive pinion turning torque, and compare with specified value. If turning torque is not within specified value, ensure companion
flange self-locking nut is tightened within specification and oil seal is correctly installed.
Fig. 46 Checking Differential Gear Backlash
Fig. 47 Lockpin Installation
5. Adjust differential gear backlash as follows:
a. Assemble side gears, side gear spacers, pinion gears and pinion washers into differential case.
b. Temporarily install pinion shaft.
NOTE: Do not drive in lockpin at this time.
c. While locking side gear with wedge, measure differential gear backlash with dial indicator as shown. Measurement should be made for both
gears individually.
d. Gear backlash should not exceed 0.008 inch (.2 mm). If backlash exceeds limits, adjust by installing thicker side gear spacers.
e. After adjustment, ensure differential gear rotates smoothly.
f.
If backlash cannot be adjusted within acceptable range, replace side gear and pinion gear as a set.
6. Align pinion shaft lockpin hole with differential case lockpin hole, and drive in lockpin.
7. Stake lockpin with punch at two points as shown.
8. Clean drive gear attaching bolts, then using a M10 X 1.25 tap, remove adhesive adhering to threaded holes of drive gear. Clean remaining material
out of drive gear using compressed air.
9. Apply multipurpose adhesive Mopar Loctite No. 271 or equivalent to threaded holes of drive gear.
