10. 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 the final assembly of integral
rear axle assemblies.
Use a drive pinion bearing adjustment shim as a gauge for shim selection.
After the proper shim thickness has been determined, remove the Gauge Tube.
11. CAUTION: Check the splines on the pinion stem to be sure they are free of burrs. If burrs are evident, remove them by using a fine crocus cloth,
working in a rotational motion. Wipe the pinion clean.
NOTE: The same differential pinion bearing used in the following procedure must be used in the final assembly of the axle.
NOTE: Make sure the press load is not applied to the bearing cage.
Place the selected shim(s) on the pinion and press the bearing until it is firmly seated on the shaft using the special tools.
