DIFFERENTIAL INSTALLATION
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 14.
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 115-135 Lb-Ft (155-183 N-m). Check
backlash after torquing cap bolts.

Oil Scoop
Mounting
1. Assemble oil scoop onto differential case. See
Figure 12. Clean and coat bolts with Loctite #277
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. Tilt differential slightly so ring gear
clears straddle bearing support.
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 13.
