Carrier and Differential Case Reassembly
To install the differential case into the carrier, two
different methods may be used.
One method uses the dummy differential bearing
to figure the shim thickness. The other uses the
existing differential outboard spacer. Both of these
methods will be explained; however, keep in mind
that using the existing shims can save a lot of time
and reduces the number of times the differential
case is installed and then removed from the carrier.
The more times the process is repeated, the
greater the risk for damaging the carrier, the case,
the differential bearings, or the gear set.
NOTE: When using dummy bearings, the differ-
ential case must not have any bearings or the
ring gear attached.
1. Slide the dummy bearing with the deep
chamfer towards the case onto the trunnion
(Figure 89).
5. Slide the differential case to the right and take
a reading (Figure 90). Do this a couple of
times to make sure that the same reading,
.340" for example, is obtained.
NOTE: This is called the total travel of the
differential case. Total travel means that the case
did not touch the pinion and is measured from
shoulder to shoulder of the differential case in
the differential bore. Be sure to write down this
number for later reference.
6. Pull the case from the carrier and remove the
dummy bearings.
8. To install the ring gear on the case, start all of
the ring gear bolts.
9. Press the ring gear onto the case (Figure 91).
2. Slide the differential case with the dummy
bearing into the carrier. The case should slide
back and forth.
3. Push the case as far to one side as possible.
4. Attach a dial indicator to the carrier so that
the tip of the indicator is against the flange
side of the case. Set the dial indicator to zero.
Do not use the ring gear bolts
to pull the ring gear onto the case. This will
stretch the bolt threads and the bolts may not
hold their required torque.
