REAR FINAL DRIVE

NOTE:

Side gear back clearance is clearance between side gear and differential case for adjusting side gear

backlash.

Side Bearing Preload Torque

• A selection of side bearing adjusting washers is required for successful completion of this procedure.
1. Apply differential gear oil to the side bearings, and install the dif-

ferential case assembly with the side bearing outer races into

the gear carrier.

CAUTION:

Do not reuse side bearing outer race when replacing side

bearing inner race (replace as a set).

2. Insert the left and right original side bearing adjusting washers in

place between side bearings and gear carrier using Tool.

3. Align the matching mark on the side bearing cap with the match-

ing mark on the gear carrier.

4. Install the side bearing caps and tighten the side bearing cap

bolts to the specified torque. Refer to 

DLN-225, "Disassembly

and Assembly"

.

5. Turn the differential assembly several times to seat the side

bearings.

6. To determine side bearing preload torque, measure the pulling

force of the differential assembly at the drive gear bolt using

Tool.

NOTE:

If pulling force of the differential assembly at the drive gear bolt

is within specification, side bearing preload torque will also be

within specification. Refer to 

DLN-225, "Disassembly and Assembly"

.

7. If the pulling force is outside the specification, use a thicker or

thinner side bearing adjusting washer to adjust. Refer to 

DLN-

225, "Disassembly and Assembly"

.

CAUTION:

Select a side bearing adjusting washer for right and left

individually.

8. Record the total amount of washer thickness required for the correct side bearing preload torque.

Drive Pinion Height

1. Make sure all parts are clean and that the bearings are well

lubricated.

2. Assemble the drive pinion bearings onto the Tool.

• Drive pinion front bearing; make sure the J-34309-3 drive

pinion front bearing seat is secured tightly against the J-

34309-2 gauge anvil. Then turn the J-34309-5 drive pinion

front bearing pilot to secure the drive pinion bearing in its

proper position.

• Drive pinion rear bearing; the J-34309-8 drive pinion rear

bearing pilot is used to center the drive pinion rear bearing

only. The J-34309-4 drive pinion rear bearing locking seat is

used to lock the drive pinion rear bearing to the assembly.

• Installation of J-34309-9 and J-34309-16; place a suitable

2.5 mm (0.098 in) thick plain washer between J-34309-9 and

J-34309-16. Both surfaces of J-34309-9 and J-34309-16 must

be parallel with a clearance of 2.5 mm (0.098 in).

3. Install the drive pinion rear bearing inner race into the gear car-

rier. Then insert the drive pinion height adjusting washer selec-

tor tool, J-34309-1, gauge screw assembly.

If the pulling force is less than the specification:

Use a thicker side bearing adjusting washer.

If the pulling force is greater than the specification:

Use a thinner side bearing adjusting washer.

4. Assemble the drive pinion front bearing inner race and the J-

34309-2 gauge anvil. Assemble them together with the J-34309-

1 gauge screw in the gear carrier. Make sure that the drive pin-

ion height gauge plate, J-34309-16, will turn a full 360

°. Tighten

the two sections together by hand.

5. Turn the assembly several times to seat the drive pinion bear-

ings.

6. Measure the turning torque at the end of the J-34309-2 gauge

anvil using Tool.

7. Place the J-34309-11 drive pinion height adapter onto the gauge

plate and tighten it by hand.

CAUTION:

Make sure all machined surfaces are clean.

8. Position the side bearing discs, Tool, and arbor firmly into the

side bearing bores. Install the side bearing caps and tighten the

side bearing cap bolts to the specified torque. Refer to "

DLN-

225, "Disassembly and Assembly"

9. Select the correct standard drive pinion height adjusting washer

thickness. Select by using a standard gauge of 3 mm (0.12 in)

and your J-34309-101 feeler gauge. Measure the distance

between the J-34309-11 drive pinion height adapter, including

the standard gauge and the arbor.

10. Write down the exact measurement (the value of feeler gauge).

11. Correct the drive pinion height adjusting washer size by referring

to the drive pinion “head number”.

There are two numbers painted on the drive pinion. The first

one refers to the drive pinion and drive gear as a matched

set. This number should be the same as the number on the

drive gear. The second number is the drive pinion “head

number”. It refers to the ideal drive pinion height from stan-

dard for quietest operation. Use the following chart to

determine the correct drive pinion height adjusting washer.

12. Select the correct drive pinion height adjusting washer. Refer to 

DLN-225, "Disassembly and Assembly"

.
