14) Adjusting the side bearing retainer shims
(1) The hypoid driven gear backlash and side
bearing preload can be adjusted by the side
bearing retainer shim thickness.
(2) Install the differential assembly into differen-
tial carrier in the reverse order of disassembly.
(3) Install the side bearing retainer shims to re-
tainers RH and LH from which they were re-
moved.
NOTE:
Replace the broken or corroded side retainer shim
with a new one of same thickness.

(4) Align the arrow mark on differential carrier
with the mark on side retainer during installation.

aged by bearing roller.

(6) Measure the hypoid driven gear to drive pin-
ion backlash. Set the magnet base on differen-
tial carrier. Align the contact point of dial gauge
with tooth face of hypoid driven gear, and move
hypoid driven gear while holding drive pinion
still. Read the value indicated on dial gauge.
If the backlash exceeds 0.2 mm (0.08 in), re-
duce the thickness of shim on the back face of
hypoid driven gear and increase the thickness of
shim on the tooth face of hypoid driven gear. If
the backlash is less than 0.1 mm (0.004 in), in-
crease the thickness of shim on the back face of
hypoid driven gear and reduce the thickness of
shim on the tooth face of hypoid driven gear.
