1. Perform the operations listed below and as de-
scribed in your shop manual that apply to your vehicle. The axle
shafts should be pulled out about six inches for differential case
removal.
2. Using a center punch, mark both the carrier and
bearing cap on the ring gear side with one punch mark each
and on the other side with two marks. The caps are not in-
terchangeable, because each one is line-bored with the carrier.
These marks are very important to correct re-assembly!
3. Rock the ring gear back and forth to get a “feel” for
the amount of backlash present. This amount of rotation will be
re-checked when the differential case is installed to determine if
it has been done correctly.
4. Remove the bearing caps and then the differen-
tial case and shims from the carrier as described in the shop
manual (some axle designs may require the use of a carrier
spreader tool). Be sure to put a small grind mark on each shim or
tag them so that they can be replaced on the same side.
5. Remove the differential bearing race from the side
with one punch mark first. Put a very small grind mark on the
outside of it, or use a tag. Be sure that you can identify it for
proper re-assembly on the same side.
6. Remove the other bearing race.
7. Remove the ring gear from the case. It may need to
be tapped off with a brass mallet (see the shop manual). Mark it
so that it can be re-installed in the same rotational orientation as
when removed.
8. Proceed to Section 2 (next) for LOCK-RIGHT Installa-
tion.
