Note: To install the wheel differential assembly, properly

setup the gear pattern and set the differential bearing

preload. This will require the use of the following Spicer

tools or equivalent. These tools will allow you to align

the bearing adjuster assembly to the carrier. This tool

(part number 513061) will also gage the adjustment for

the differential bearing preload and assist in setting the

backlash. Below you will find detailed instructions

explaining each procedure.

1. The bearing adjustment tool is made up of a threaded

rod, two nuts, two washers and two adjustment plates.

Fit one adjustment plate to the plain half threaded cup.

Fit the other adjustment plate to the flange half cup.

The adjustment rings will fit into slots of the threaded

bearing cups stamped adjustment ring.

2. Connect the adjuster plates using the threaded rod,

washers and nuts. Tighten the nuts on the rod to
hold the threaded cups in place. Carefully lower the
wheel differential and ring gear assembly into the
carrier.

Note: There are two ways to make sure that the threaded cups

are seated properly. If there is a misalignment, reinstall
the differential assembly at a slightly different angle.

threads and the cup threads.
