gear carrier and install side bearing caps on gear carrier.

CAUTION:

Do not tighten side bearing cap bolts at this point. This

allows further tightening of side bearing adjusters.

7. Tighten each side bearing adjusters using adjuster tool. Perform

the following adjustments.

• Adjusting backlash of drive gear and drive pinion. Refer to

DLN-331, "Inspection and Adjustment"

.

• Check total preload. Refer to 

DLN-331, "Inspection and

Adjustment"

.

• Check tooth contact. Refer to 

DLN-321, "Disassembly and

Assembly"

.

8. Apply a bead of sealant to the mating surface of the carrier

cover as shown.

• Use Genuine Silicone RTV or equivalent. Refer to
