3. Measure clearance between side gear and differential case
with washers following the procedure below:
a. Set Tool and dial indicator on side gear.
b. Move side gear up and down to measure dial indicator deflec-
tion. Always measure indicator deflection on both side gears.
Clearance between side gear and differential case with
washers:
0.1 - 0.2 mm (0.004 - 0.008 in)
SMT611A
c. If not within specification, adjust clearance by changing thick-
ness of side gear thrust washers.
