2. 2. 2. 2. 2. Be sure side bearing cups are seated on bearing
cones. Assemble differential bearing caps, with
match marks in proper location. Clean bearing cap
bolts and washers and coat threads with Loctite
#277. Install bearing cap bolts and tighten enough
to draw bolt head into contact with bearing cap,
eliminating visible space between differential bearing
cap and carrier housing. Do not torque the cap
bolts at this time.
4. 4. 4. 4. 4. Loosen adjusting ring on tooth side of ring gear one
notch and tighten adjusting ring on flange side of
ring gear one notch. Repeat process until backlash
is eliminated. Tighten adjusting ring on tooth side
of the ring gear until the ring gear and pinion
backlash matches the backlash etched on the
ring gear. This adjustment sets both the backlash
and the bearing preload.
5. 5. 5. 5. 5. Check ring gear and pinion backlash in four equally
spaced positions around the ring gear with a dial
indicator as shown. See F

cap bolts to 295-340 Lb-Ft (397-460 N-m). Check
backlash after torquing cap bolts.
