ADJUSTMENT
Differential Side Bearing Preload

When adjusting differential side bearing preload, select adjust-
ing shim for differential side bearing. To select adjusting shim,
measure clearance “L” between transaxle case and differential
side bearing outer race. Refer to MT-108, "
DIFFERENTIAL
SIDE BEARING ADJUSTING SHIM(S)" .
CAUTION:
Up to 2 adjusting shims can be selected.

Calculate dimension “L” (thickness of adjusting shim) using the
following procedure to satisfy specification of preload for differ-
ential side bearing.
1. Using depth micrometer and straightedge, measure dimension
“L
1 ” between transaxle case end face and mounting face of
adjusting shim.
2. Install differential side bearing outer race onto differential side
bearing on final gear side. Holding lightly differential side bear-
ing outer race horizontally by hand, rotate final gear five times or
more (for smooth movement of bearing roller).

4. Using the suitable drift, drive the adapter case oil seal until it
becomes flush with the case end.
CAUTION:

When checking the total preload torque, measure it with-
out the oil seal, then install the oil seal.

Do not reuse the oil seal.

Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of the oil seal.
5. Apply recommended sealant on drain plug and install it to the
adapter case. Refer to TF-59, "
COMPONENTS" .
6. Apply multi-purpose grease lightly and evenly onto an O-ring,
and install it to the adapter case.
CAUTION:
Do not reuse the O-ring.
7. Install the adapter case to the transfer case, and apply anti-cor-
rosive oil onto threads and seats on the mounting bolts. Tighten
to the specified torque.
8. Check backlash, preload torque, tooth contact, and companion
flange runout. Refer to TF-60, "
ASSEMBLY INSPECTION" .
CAUTION:
Measure the total preload torque without the oil seal.
