Differentials
NOTE:
Be sure to wipe off red lead completely after
adjustment is completed.
20) If proper tooth contact is not obtained, once
again adjust the drive pinion height and the differ-
ential side bearing preload (already mentioned)
and the hypoid gear backlash.
(1) Drive pinion height
ST1 498447150 DUMMY SHAFT
ST2 498505501 DIFFERENTIAL GAUGE
T = To + N − 0.05 (mm)
where
T = Thickness of pinion height adjusting shim
(mm)
To = Thickness of shim originally installed
(mm)
N = Reading of thickness gauge (mm)
(2) Differential side bearing preload
Screw in side (left-side) holder until light contact
is made with ST.
Back off side (left-side) holder approximately 1
1/2 teeth of holder, and tighten left-side holder
by approximately 2 teeth (approximately 1 1/2 +
1/2 teeth).
[Back off amount of side (left-side) holder + 1/2
tooth.]
This + 1/2 tooth gives preload.
