FRONT AND REAR AXLE DRIVE PINION AND BEARINGS MAINTENANCE
Remove dial indicator (20), 2 bearing caps, depth gaging tools, and front and rear bearings
(1 O and 12) from housing (4).
Check rear face of drive pinion, or painted marking on drive pinion shaft
pinion code number. Calculate drive pinion shim thickness to be used.
Table 6-2. Determining Drive Pinion Shim Requirements
being installed, for
(a) If drive pinion has no plus (+) or minus (-), use exact shim thickness as recorded in
(b) If drive pinion is stamped or painted with a plus (+) number, add that many thousandths to
thickness recorded in step 8.
(c) If drive pinion is
If reading from step 8 was 0.019 in. (0.483 mm) and
drive pinion was stamped +2, correct shim
0.019 in. + 0.002 in. = 0.021 in.
(0.483 mm + 0.057 mm = 0.534 mm)
stamped or painted with a minus (-) number, subtract that many
thickness recorded in step 9.
If reading from step 8 was 0,031 in, (0.787 mm),
and drive pinion was stamped -3, correct shim
0.031 in. -0.003 in. = 0.028 in.
(0.787 mm -0.076 mm = 0.711 mm)
