REAR FINAL DRIVE ASSEMBLY
●
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.
●
Front Pinion Bearing — make sure the J34309-3, front pin-
ion 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.
3.
Place the pinion preload shim selector tool gauge screw assem-
bly, J34309-1, with the pinion rear bearing inner cone installed,
into the final drive housing.
4.
Install the J34309-2 gauge anvil with the front pinion bearing into
the final drive housing and assemble it to the J34309-1 gauge
screw. Make sure that the J34309-16 gauge plate will turn a full
360 degrees, and tighten the two sections by hand to set bear-
ing preload.
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 J34309-12 “H233B” pinion height adapter onto the
gauge plate and tighten it by hand.

PINION HEIGHT ADJUSTING WASHER SELECTION
CAUTION:
Make sure all machined surfaces are clean.
8.
Position the J25269-18 side bearing discs and the arbor into the
side bearing bores.
9.
Install the bearing caps and tighten the bearing cap bolts.
10. Select the correct standard pinion height adjusting washer thick-
ness using a standard gauge of 2.5, 3.0, or 3.5 mm (0.098,
0.118, or 0.138 in) and the J34309-101 feeler gauge.
Measure the distance between the J34309-12 “H233B” pinion
height adapter and the arbor.
11. Write down the exact total measurement (the value of feeler
gauge).
12. Correct the drive pinion height adjusting washer size by referring
to the “pinion head height number”.
●
There are two numbers painted on the drive pinion. The first
one refers to the pinion and ring gear as a matched set and
should be the same as the number on the ring gear. The sec-
ond number is the “pinion head height number”, and it refers
to the ideal pinion height from standard for the quietest opera-
tion. Use the following chart to determine the correct drive
pinion height adjusting washer. Refer to
SPD286A

TOOTH CONTACT
Gear tooth contact pattern check is necessary to verify correct relationship between ring gear and drive pinion.
Hypoid gear sets which are not positioned properly in relation to one another may be noisy, or have short life,
or both. With a pattern check, the most desirable contact for low noise level and long life can be assured.
1.
Thoroughly clean ring gear and drive pinion teeth.
2.
Sparingly apply a mixture of powdered ferric oxide and oil or
equivalent to 3 or 4 teeth of ring gear drive side.
3.
Hold companion flange steady by hand and rotate the ring gear
in both directions.
