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

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.
