DIFFERENTIAL ASSEMBLY

4.

If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height [dimension (X)].

• If the tooth contact is near the face (face contact), or near the

heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.

• If the tooth contact is near the flank (flank contact), or near the

toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.

BACKLASH

Before inspection and adjustment, drain gear oil.

1.

Remove rear cover. Refer to 

DLN-164, "2WD : Disassembly"

.

2.

Fit a dial indicator to the drive gear face to measure the back-
lash.

• If the backlash is outside of the specified value, change the

thickness of side bearing adjusting washer.
