25-3. AXLE NO. 3 DIFFERENTIAL REPAIR (CONT)
(29) Install differential carrier preload gage (31)
on bearing cap (27) with screw (35).
(29.1) Position magnetic base of dial indicator
(32) on bearing cap (27).
(29.2) Position probe of dial indicator (32) on
differential carrier preload gage (31).
(29.3) Zero dial indicator (32).
(30) Tighten adjusting nut (30) until bearing
caps (27) expand 0.014-0.018 in. (.36-.46
mm).
(30.1) Remove screw (35), differential carrier
preload gage (31) and dial indicator (32)
from bearing caps (27).
(31) Tighten screws (26) on bearing caps (27)
to 120-137 lb-ft (163-186 Nm).
(32) Check backlash of differential (24) to
pinion shaft (10).
(33) Hold pinion shaft (10) so pinion gear (16)
does not move.
NOTE
Do not allow pinion gear to turn while
doing steps (33) thru (35).
(34) Turn differential (24) counterclockwise
until it stops to take up backlash.
NOTE
Shaft from dial indicator must be at
right (90) angle to face of tooth when
in contact.
(35) Install dial indicator (32) on face of
differential gear tooth (33).
(36) Turn differential (24) clockwise until it
stops.
NOTE
Backlash should be 0.0100.016 in.
(25-41 mm). To increase backlash,
reduce thickness of shims installed
in carrier housing.
To decrease
backlash, increase thickness of
shims.
(37) Record differential (24) to pinion shaft (10)
backlash measured on dial indicator (32).
