DIFFERENTIAL CASE

NMPD0033S03

1.

Remove side bearing inner cones.

To prevent damage to bearing, engage puller jaws in groove.

Tool number:

A ST3305S001
B ST33061000

Be careful not to confuse left- and right-hand parts. Keep bear-
ing and bearing race for each side together.

Inspection

NMPD0034

RING GEAR AND DRIVE PINION

NMPD0034S01

Check gear teeth for scoring, cracking or chipping.
If any damaged part is evident, replace ring gear and drive pinion
as a set (hypoid gear set).

DIFFERENTIAL CASE ASSEMBLY

NMPD0034S02

I

Check mating surfaces of differential case, side gears, pinion
mate gears, pinion mate shaft and thrust washers.

I

Check viscous coupling for oil leakage. If necessary, replace it
with new one.

BEARING

NMPD0034S03

1.

Thoroughly clean bearing.

2.

Check bearings for wear, scratches, pitting or flaking.
Check tapered roller bearing for smooth rotation. If damaged,
replace outer race and inner cone as a set.

Adjustment

NMPD0040

To avoid confusion while calculating bearing shims, it is absolutely
necessary to stay with the metric system. If you measure anything
in inches, the results must be converted to the metric system.
