DIFFERENTIAL ASSEMBLY
1. If ring gear was removed from the differential case,
reinstall it at this time.
• Clean the differential case and ring gear
mounting surface.
• Position the differential case on a work bench
with the machine surface down.
• Place the ring gear on the case with the
teeth facing up.
• Install bolts into the tooth side of the ring gear
and install the flat washer and nut onto the
differential case side.
NOTE: Bolts have a clearance fit in the differential
case and the ring gear mounting holes. Bolts require
correct torque to ensure proper clamp.
• When all bolts have been installed, tighten
opposite one another until one half the pre-
scribed torque is obtained
. 150-160 Lb-Ft
(204-217N-m)
NOTE: Bolt heads must be held flat against ring gear
while torque is being applied.
• Repeat the process to full torque specifications.
300-320 Lb-Ft (407-434 N-m)
2. Press bearing cones onto differential case
halves. Place bearing cups on cones during
remainder of assembly to prevent damage of
bearings.
3. Apply a small amount of hypoid axle lubricant to all
mating surfaces. This will aid in assembly by
keeping parts together and providing initial lubrica-
tion.
4. Place gear thrust washer and differential side gear in
differential case flange half.
5. Assemble pinion mates and pinion mate thrust
washers onto differential cross shaft. Place assem-
bly into flange half differential case.
6. Place remaining differential side gear and thrust
washer in position on differential pinion mates.
7. Assemble case halves, making sure match marks are
lined up.
8. Install differential case bolts. Tighten alternately
and torque evenly to 180-200 Lb-Ft (244-27N-m).
NOTE: If old bolts are used, coat threads with Loctite
#277 before installing.
