1. Three differential cases are used with the W Model
carriers, depending on the ratio. Two of the cases
have two oil pick-up plates attached. Clean and coat
bolts with Loctite #271 or its equivalent. Assemble
and torque bolts to 7-9 Lb-Ft (9-12 N-m)
CAUTION: Differential assembly must be
aligned within bearing bores before preload is applied
or damage to bearings could occur.
2. Install ring gear and differential assembly into
carrier housing.
CAUTION: To avoid damage of the ring gear and
pinion, care should be used when installing the ring
gear differential assembly into the carrier housing.
3. Be sure side bearing cups are seated on bearing
cones. Assemble differential bearing caps, with
match marks in proper location. Clean differential
bearing cap bolts and washers and coat threads
with Loctite #277 or its equivalent. Install bearing
cap bolts and tighten enough to eliminate visible
space
between differential bearing cap and
carrier housing. Do not torque the cap bolts at
this time.
4. Install adjusting rings. Tighten both adjusting rings
until end play is eliminated and there is backlash
between the ring gear and pinion.
See Figure 11.

5. Loosen adjusting ring on tooth side of ring gear 1
notch and tighten adjusting ring on flange side of
ring gear 1 notch. Repeat process until backlash is
eliminated. Tighten adjusting ring on tooth side of
the ring gear 2 or 3 notches or until proper
backlash and side bearing preload are established.
6. Check ring gear and pinion backlash in four equally
spaced positions around the ring gear with a dial
indicator as shown.
Acceptable backlash tolerance
is .006"-.012". See Figure 12.
NOTE: If backlash tolerance varies more than .003"
(.080 mm) between the four positions, remove the
differential and determine the cause.
7. Once backlash is set, torque the differential bearing
cap bolts to 295-340 Lb-Ft (397-460 N-m) Check
backlash after torquing cap bolts.
