Pinion and Ring Gear Adjustments (All Except Dana)

FIG. 7 Pinion and Ring Gear Tooth Contact Adjustment-Integral Carrier Axles:

Two adjustments affect drive pinion and ring gear tooth contact. They are drive pinion depth and backlash (Fig. 7).

The pinion depth adjusting shims are installed between the drive pinion Head and Rear pinion bearing, therefore, adding shims moves the drive pinion towards the ring gear, and removing shims moves the drive pinion away from the ring gear.

On Ford integral axles, backlash is adjusted by adding or removing shims between the differential case side bearings and carrier housing.
