  1. 6.

    NOTE: Drive pinion bearing adjustment shims must be flat and clean.
    NOTE: A slight drag should be felt for correct drive pinion bearing adjustment shim selection. Do not attempt to force the drive pinion bearing adjustment shim between the gauge block and the gauge tube. This will minimize selection of a drive pinion bearing adjustment shim thicker than required, which results in a deep tooth contact in the final assembly of integral axle assemblies.

    Use a drive pinion bearing adjustment shim as a gauge for drive pinion bearing adjustment shim selection.
