DRIVESHAFT SHIMMING
IMPORTANT:
If 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 drive-
shaft, 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:
Degrease pinion and driveshaft
tapers prior to assembly. Check tapers for any
damage or material transfer. Replace any dam-
aged components before proceeding.
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).
IMPORTANT:
The original pinion nut may be
used for shimming, but must
NOT
be used in final
assembly.
Select collar, P/N 341440, and the correct shim
gauge bar:
•
“M2”:
Shim gauge bar, P/N 349957
•
“L2”:
Shim gauge bar, P/N 328367
Slide the collar onto the driveshaft with large end
in contact with the bearing housing.
Insert the assembled driveshaft into the tool base
and tighten preload screw against the driveshaft
until groove on the spring-loaded plunger is flush
with end of threads. Tighten locking ring on pre-
load screw.
Rotate the driveshaft several revolutions to seat
bearings.
Lay the tool base on its side. Position the shim
gauge bar against guide pins of the tool base.
