1
Position the special tool.

Install the differential side bearing caps.

Install the four differential side bearing cap bolts.
8. 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.
Use a drive pinion bearing adjustment shim as a gauge for shim selection.
^
After the correct shim thickness has been determined, remove the Gauge Tube.
