NOTE:

Drive pinion bearing adjustment shims must be flat and clean.

NOTE:

A slight drag should be felt for correct shim selection. Do not attempt to
force the pinion shim between the Gauge Block and the Gauge Tube. This
will minimize selection of a pinion shim thicker than required, which
results in a deep tooth contact in final assembly of integral rear axle
assemblies.
