Removal (Fig. 7)
1. Park vehicle on a level surface, shut engine off, re-
move key from ignition switch and apply parking brake.
Block rear wheels to prevent the vehicle from moving
unexpectedly.
2. Drain front differential oil into a suitable container by
removing the drain plug. Install drain plug after draining.
3. Unplug wire harness connector from front differen-
tial.
4. Remove both CV axle assemblies from the front dif-
ferential (see CV (Constant Velocity) Axle Assembly in
this section).
5. Remove cap screw and lock nut that secure drive-
shaft yoke to the front differential input shaft. Separate
differential driveshaft yoke from the differential input
shaft (see Front Differential Driveshaft in this section).
CAUTION
Support front differential during removal to pre-
vent personal injury from falling and damage to
the differential.
6. Remove four (4) flange head screws (item 4) and
lower differential plate (item 17) that secure the differen-
tial to the frame.
7. Slide front differential assembly forward to allow re-
moval of front differential driveshaft yoke from differen-
tial input shaft. Slide driveshaft yoke from input shaft and
position driveshaft away from differential.
IMPORTANT: Make sure to not damage brake lines,
electrical harness, control cables or other parts
while removing the differential.
8. Tip differential toward left side (driver side) of ve-
hicle. Remove differential assembly toward the right
side (passenger side) of the vehicle.

onto mounts.
2. Position front differential assembly to the vehicle
frame from the right side (passenger side) of the vehicle.
Make sure that larger offset in differential plate is placed
to allow access to the differential drain plug.
3. Apply antiseize lubricant to input shaft of differential.
Slide driveshaft yoke onto differential input shaft.
4. Move differential toward rear of vehicle and align
holes in frame, mounts, upper differential plate and dif-
ferential.
5. Secure front differential to the frame with lower differ-
ential plate (item 17) and four (4) flange head screws
(item 4).
6. Secure driveshaft yoke to the differential with cap
screw and lock nut (see Front Differential Driveshaft in
this section).
7. Install both CV axles to the front differential (see CV
(Constant Velocity) Axle Assembly in this section).
8. Connect wire harness connector to front differential.
