REAR FINAL DRIVE ASSEMBLY
1.
Make sure all parts are clean. Also make sure the bearings are
well lubricated with light oil or “DEXRON
TM
” automatic trans-
mission fluid.
2.
Place the differential carrier, with side bearings and bearing
races installed, into the final drive housing.
3.
Put the side bearing adjusting shim in place.
CAUTION:
Side bearing adjusting shim is placed on either the right or
left depending upon final drive gear ratio. Be sure to place it
on the correct side.
4.
Use Tool to place original carrier side bearing adjusting shims on
the carrier end, opposite the ring gear.
5.
Install the side bearing caps in their correct locations using the
matchmarks made during removal, and tighten the bearing cap
bolts to specification.
6.
Turn the carrier several times to seat the bearings.
7.
Measure the turning resistance of the differential carrier assem-
bly at the ring gear retaining bolts with Tool.

8.
If the turning resistance is not within the specification, correct as
follows:
●
If the turning resistance is less than the specified range, install
thicker side bearing adjusting shims.
●
If the turning resistance is greater than the specification,
install thinner side bearing adjusting shims.
9.
Record the total amount of shim thickness required for the cor-
rect carrier side bearing preload.
10. Remove the carrier from the final drive housing. Save the
selected adjusting shims for later use during the assembly of the
final drive unit.
PINION GEAR HEIGHT
1.
Make sure all parts are clean and that the bearings are well
lubricated.
2.
Assemble the pinion gear bearings into the pinion preload shim selector Tool, J34309.
●
Front pinion bearing — make sure the J34309-3 front pinion
bearing seat is secured tightly against the J34309-2 gauge
anvil. Then turn the front pinion bearing pilot, J34309-5, to
secure the bearing in its proper position.
●
Rear pinion bearing — the rear pinion bearing pilot, J34309-
8, is used to center the rear pinion bearing only. The rear pin-
ion bearing locking seat, J34309-4, is used to lock the bearing
to the assembly.

REAR FINAL DRIVE ASSEMBLY
3.
Install the pinion rear bearing inner cone into the final drive
housing. Then place the pinion preload shim selector Tool,
J34309-1, on gauge screw assembly.
4.
Assemble the front pinion bearing inner cone and the J34309-2
gauge anvil. Assemble them together with the J34309-1 gauge
screw in the final drive housing. Make sure that the pinion height
gauge plate, J34309-16, will turn a full 360 degrees. Tighten the
two sections together by hand.
5.
Turn the assembly several times to seat the bearings.
6.
Measure the turning torque at the end of the J34309-2 gauge
anvil using Tool.
7.
Place the J34309-11 pinion height adapter onto the gauge plate
and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.

Pinion Height Adjusting Washer Selection
1.
Now, position the side bearing discs, J25269-4, and arbor firmly
into the side bearing bores.
2.
Install the side bearing caps and tighten the side bearing cap bolts to proper torque.
3.
Select the correct standard pinion height adjusting washer thick-
ness. Select by using a standard gauge of 3 mm (0.12 in) and
J34309-101 feeler gauge. Measure the distance between the
J34309-11 pinion height adapter including the standard gauge
and the arbor.
4.
Write down the exact measurement (the value of feeler gauge).
5.
Correct the pinion height adjusting washer size by referring to
the “pinion head number”.
●
There are two numbers painted on the pinion gear. The
first one refers to the pinion and ring gear as a matched
set. This number should be the same as the number on
the ring gear. The second number is the “pinion head
height number”. It refers to the ideal pinion height from
standard for quietest operation.
●
Use the following chart to determine the correct pinion
height adjusting washer:
