Driveshaft Shimming
NOTICE
If a new pinion gear is needed, replace gear
set before shimming.
Pinion gear backlash is achieved by using shims
between the driveshaft bearing housing and the
thrust washer. When installing a new thrust bear-
ing or washer, bearing housing, pinion, or drivesh-
aft, it is necessary to properly shim the assembly
to restore factory clearance.
Use Driveshaft Shimming Tool, P/N 5005925.
Shim gauge bars are precision made and should
be handled carefully. The length of each bar is
stamped near the part number. This dimension is
0.020 in. (0.508 mm) shorter than the actual
shimmed length of the driveshaft.
IMPORTANT:
Clean pinion and driveshaft be-
fore assembly. Replace any damaged parts.
Assemble the driveshaft bearing housing, thrust
washer, thrust bearing, and pinion onto the drive-
shaft. Use Driveshaft Seal Protector, P/N 318674,
when installing or removing the bearing housing.
Lightly coat the threads of the pinion nut with out-
board lubricant and tighten to a torque of 100 to
110 ft. lbs. (136 to 149 N·m).
