1) Install drive pinion in differential carrier. Install
spacer, pinion front shim(s) and front pinion bearing. DO NOT install
oil seal. Install pinion flange, washer and retaining nut. Tighten nut
to specification. See TORQUE SPECIFICATIONS table.
2) Check pinion rotating torque. Rotating torque must be
within specification. Correct specification is 3.5-4.3 INCH lbs. (.40-
.48 N.m) without oil seal. Adjust rotating torque by replacing drive
pinion front shims or spacer.
3) Once correct rotating torque is obtained, install oil
seal. Coat seal lip with grease. Install pinion flange so alignment
marks are correct. Apply light coat of grease to contact area of
pinion flange washer.
4) Install new retaining nut. Recheck pinion rotating torque.
Rotating torque must be within specification.
SIDE BEARING
1) Press side bearings onto differential case. Install outer
races. Install differential case into differential carrier. Align
bearing cap index marks, and snug carrier cap bolts. Ensure outer
races and bearing caps are installed in original location. Tighten
bearing cap bolts finger tight.
2) Install side bearing nuts. Tighten bearing cap bolts. See
TORQUE SPECIFICATIONS table. Rotate bearing nuts in and out until
rotation is smooth. Temporarily tighten side bearing nuts to preload
side bearings. See TORQUE SPECIFICATIONS table. Adjust ring gear
backlash.
RING GEAR BACKLASH
1) Lock drive pinion in place. Using dial indicator, check
ring gear backlash at heel of ring gear tooth. Measure at 4 locations
of ring gear. Gear backlash must be within specification. See RING
GEAR BACKLASH SPECIFICATIONS table.

2) If backlash is less than specification, loosen side
bearing nut at back of ring gear and tighten side bearing nut on tooth
side of ring gear by same amount. If backlash is beyond specification,
loosen side bearing nut at tooth side of ring gear and tighten side
bearing nut at back of ring gear by same amount.
3) After adjusting backlash, tighten both side bearing nuts
half the distance between center of 2 neighboring holes on side
bearing nut. Recheck backlash. Ensure bearing cap bolts are tightened
to specification. See TORQUE SPECIFICATIONS table.
4) Lock plates are of 2 designs for hole location of side
bearing nuts. Install proper type lock plate. Tighten lock plate bolt
to specification. See TORQUE SPECIFICATIONS table. Check gear tooth
contact using paint impression method. See GEAR TOOTH CONTACT PATTERNS
in this article.
RING GEAR RUNOUT
Using dial indicator, measure runout at back side of ring
gear. Runout must be within .002" (.05 mm). If runout is excessive,
change ring gear-to-differential case mounting position. Recheck
