The pinion bearing is pressed into place over the selective shim in order to position the pinion correctly in the axle carrier housing. All service bearings for 8.6" axles from 1999 to 2009 are those used on 2007-current C/K trucks. The bearing must be installed over the length of the pinion shaft, and seated against the shim. J-22828 and a hydraulic press are used to install this bearing without contacting the bearing roller cage.
