30.Install L.H. axle shaft assembly:
A. Thoroughly clean mating surface of differential
carrier and side cover (Item 1).
B. Insert selected shims (Item 2) into housing of side
cover. NOTE: The thickest shim should be inserted
against the bearing.
C. Install axle shaft assembly and tighten cap
screws (Item 1) to a torque from 18.5 to 22 ft–lb (24.5
to 29.5 N–m).
31.Measure backlash of ring gear through window on
transaxle case. Using a dial indicator, check ring gear
backlash in three equally spaced points. Backlash
should be .0031 to .0071 in. (0.08 to 0.18 mm) and must
not vary more than .0019 in. (0.05 mm) at the points
checked. If backlash is not in this range, replace shim
set in end of differential carrier:
A. If less than target range, decrease total thickness
of shim set until correct backlash is achieved.
B. If exceeds the target range, increase total thick -
ness of shim set until correct backlash is achieved.
NOTE: The thickest shim should be installed
against the bearing.
