FORWARD-REAR AXLE DIFFERENTIAL - CONTINUED
ASSEMBLY - CONTINUED
The adjustments made on the differential carrier assembly are performed to establish the proper gear
tooth contact. Correct contact will result in a long wearing, quiet running, forward-rear axle assembly.
There are five adjustments to be made and these adjustments are performed as the carrier is assembled.
The adjustments are:
Preloading the ring and pinion gear cone bearings
Establishing the pinion nominal dimensions
Setting gear lash
Preloading the differential bearings
Checking the gear tooth contact
Ring and pinion gear cone bearings preload is established by choosing the correct size spacer that is
located between the bearings and tightening the drive pinion nut. The spacer is available in different
thicknesses to obtain correct bearing preload.
Steps 55 thru 61 outline the procedure for establishing correct bearing preload.
