Carrier Assembly
Remove Differential Carrier
Note: The removal of the forward carrier does not require dis-
connecting of the inter-axle driveline and removal of the
output shaft yoke assembly as most other Spicer tan-
dems require.
Standard Differentials
1. Block the vehicle.
2. Drain axle lubricant.
3. Disconnect driveline.
4. Disconnect lead wires to the selector switch and air
line at shift cylinder.
5. Remove axle shafts.
WARNING:
Do not lie under carrier after fasteners are removed. Use
transmission jack to support differential carrier assembly
prior to loosening fasteners.
6. To remove axle shaft, remove axle stud nuts.
(If used, remove lock washers and taper dowels.)
7. Remove axle shafts.
Note: All models in this publication use axle shafts with
unequal lengths. Axle shafts may also be location spe-
cific with various wheel equipment. Do not misplace axle
shafts from their intended location. Identify left and right
shafts for reference during reassembly.
TIP: If necessary, loosen dowels by holding a brass
drift in the center of the shaft head and striking drift
with a sharp blow with a hammer.
CAUTION:
Do not strike the shaft head with a steel hammer. Do not use
chisels or wedges to loosen shaft or dowels.
8. Remove carrier cap screws, nuts, and lock washers.
9. Remove differential carrier assembly.
Install Differential Carrier
Before installing carrier assembly, inspect and thoroughly
clean interior of axle housing using an appropriate solvent
and clean rag.
1. Apply Spicer approved RTV compound on axle
housing mating surface as shown in the illustration.
Completely remove all old gasket material prior to
applying new material. Compound will set in 5 min-
utes. Install carrier before compound sets or reapply.
TIP: To assist in installing complete differential car-
rier use two pieces of threaded rod (M16 X 1.5)
threaded into carrier cap screw holes. Rod should be
approximately 6" long. Use these to pilot the carrier
into the housing.
2. Install carrier to housing, lock washers, cap screws
and nuts. Torque to proper specification. Torque to
250–290 lb-ft. (339–393 N•m).
3. Install axle shafts and axle stud nuts. (If used, also
install lock washers and tapered dowels.)
4. Add axle lubricant. Fill to bottom of filler hole.
5. Connect driveline, making sure all yokes are in
phase. Lubricate u-joints.
