f. Place removed plain half side gear on top as
shown in Figure 4.10. Use depth gauge to
determine "A", distance from differential case
half flange to backside of differential side gear.
Take four readings. Average readings for
result. Figure 4.10.
g. Determine clearance dimension: B-A=(C-D)-A.
Clearance dimension must be greater than
0.05 mm and less than 0.15 mm.
h. Use proper shim thickness to achieve
clearance specified in step G.
i. Assemble friction discs in differential case
using sequence in step C including shims.
Make sure discs are lubricated.
j. Drop side gear spline through disc pack.
k. Repeat steps "A" through "I" for the plain
differential case half.
l. Follow steps 9 through 11 to assemble
differential case.

Check Rotating Resistance
of Differential Gears
(Not Limited Slip)
NOTE
Make tool to check rotating resistance of the
differential gears, 50 lb-ft (68 N•m). The tool can
be made from a sun gear that matches the spline
of the differential side gear. Figure 4.11.

1. Place differential case assembly in a vise with soft
metal covers on the vise jaws. Install the tool into
differential until splines of tool and one side gear
are engaged. Figure 4.12.
