Tie the side bearing shims to their respective
bearing caps and cups to prevent misplacement
whenever the differential is removed. This is
done if the bearings are in good condition and
are to be re-used.
Differential Side Bearing Removal
A puller (J-2497) is used to remove the side
bearing cones from the differential case (Fig.
12). When using this tool, be sure it pulls on
the bearing cone in such a manner that the rollers
are free. If the puller bears on the roller cage,
it will damage the bearing.

Ring Gear Removal
Remove the cap screws that attach the ring gear
to the differential case.
Using a brass drift, tap the ring gear from
the case. Do not nick the ring gear face of the
differential case or drop the gear.
CAUTION: Do not chisel or wedge the
ring gear from the case.
Differential Pinion Gears and Shaft
Removal
Use a 3/16" diameter drift at least 3" long to
drive out the lock pin that holds the differential
pinion shaft in place (Fig. 13).
The pinion shaft can then be driven out and
the thrust block can be dropped out through the
differential side gear (Fig. 14).
Roll the differential pinion gears around on
the side gears until they can be lifted out
through the holes in the case. Then lift out the
side gears and their thrust washers.

INSPECTION OF REAR AXLE PARTS
The Differential Pinion Gear Shaft
Whenever one rear wheel is stuck and the other
is spinning, the differential pinion shaft is
subjected to strain. Inspect this shaft for
scoring or other signs of wear. The shaft should
be a press fit to a .010" loose fit in the
differential case.
Thrust Block
Inspect the thrust block for excessive wear,
distortion, and cracks. A thrust block that has
been worn or distorted will affect the end play
of the axle shafts. If used in this condition,
excessive end play of the axle shaft will result.
Differential Pinion Gears
Inspect the teeth of these gears for excessive
wear or chipping. Fit a new differential pinion
shaft into the gear to see if the hole is out
of round or worn. Discard the thrust washers.
New ones will be used during assembly.
