Overhaul and Assemble Wheel Differential
To prevent bearing damage, use suitable sleeve that only
contacts the inner race of the cone. A used bearing race
would be a suitable tool. This tool should have a slit cut if
the ID is the same as the flange OD.
1. Press new flange half bearing cones on differential
case halves.
2. Press new plain half bearing cones on differential
case halves.
3. Place thrust washer and side gear in flanged differen-
tial case.
4. Lubricate all differential parts.
5. Assemble side pinion and thrust washers on spider.
Place this assembly in flanged differential case. Ro-
tate gears and check for proper mesh.
6. Place side gear and thrust washer on side pinions.
7. Align punch marks and install plain case half. Install
capscrews and tighten. See Torque Chart on page
106. Check differential for free rotation by turning
side gear hub.
8. Install ring gear. Secure with bolts and nuts. Torque
nuts to 180-220 lbs. ft. (224-298 N•m)
Note: Flange half differential cases were redesigned starting
with production axles built in January 1997. New style
ring gear bolts are also required with the new style flange
case, the torque specification for this bolt is different
than the old 126219 bolt.
9. Lower assembled differential assembly into the carri-
er using a hoist and a strap. Be careful not to damage
the differential bearings lowering the assembly.
10. Install the bearing cup and bearing adjuster to the
flange half side first.
11. Install the bearing cup and bearing adjuster to the
plain half side. Use a long screwdriver or bar to lift the
differential up while installing the cup and bearing ad-
juster.
