DRIVESHAFT SHIMMING

DRIVESHAFT SHIMMING
If new pinion gear is needed,
IMPORTANT:
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
(replaces P/N 393185).
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.
