• Before inspection and adjustment, drain gear oil.

1.

Remove rear cover. Refer to

DLN-187, "AWD : Disassembly"

.

2.

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

thickness of side bearing adjusting washer.

CAUTION:

Never change the total amount of washers as it will change the bearing preload.
