ASSEMBLY INSPECTION AND ADJUSTMENT

Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Secure final drive assembly onto an attachment.
2. Remove side flanges.
3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
5. Measure total preload with the preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque

If measured value is out of the specification, disassemble it to
check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
Drive Gear Runout
1. Remove rear cover. Refer to RFD-22, "Differential Assembly" .
2. Fit a dial indicator to the drive gear back face.
3. Rotate the drive gear to measure runout.

If the runout is outside of the repair limit, check drive gear
assembly condition; foreign material may be caught between
drive gear and differential case, or differential case or drive gear
may be deformed, etc.
CAUTION:
Replace drive gear and drive pinion gear as a set.Tool number A: KV38100800 (J-25604-01)
Tool number A: ST3127S000 (J-25765-A)
Total preload torque:
2.84 - 3.75 N·m (0.29 - 0.38 kg-m, 26 - 33 in-lb)
PDIA0766J
When the preload torque is large
On pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
When the preload is small
On pinion bearings: Tighten the drive pinion lock nut.
On side bearings: Use thicker side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
Runout limit: 0.05 mm (0.0020 in)

Companion Flange Runout
1. Fit a test indicator to the inner side of companion flange (socket
diameter).
2. Rotate companion flange to check for runout.
3. If the runout value is outside the runout limit, follow the proce-
dure below to adjust.
a. Check for runout while changing the phase between companion
flange and drive pinion by 90° step, and search for the position
where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has
been changed, possible cause will be an assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if necessary.
c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
DISASSEMBLY
Differential Assembly
1. Drain gear oil, if necessary.
2. Remove side flange.
3. Remove rear cover mounting bolts.
4. Remove rear cover to insert the seal cutter between gear carrier
and rear cover.
CAUTION:

Be careful not to damage the mating surface.

Do not insert flat-bladed screwdriver, this way damage
the mating surface.
5. Using two 45 mm (1.77 in) spacers, mount carrier on the attach-
ment.
6. For proper reinstallation, paint matching marks on one side of
the bearing cap.
CAUTION:

For matching marks, use paint. Do not damage bearing
caps and gear carrier.

Bearing caps are line-board during manufacture. The
matching marks are used to reinstall them in their origi-
nal positions.Runout limit: 0.08 mm (0.0031 in)

INSPECTION AFTER DISASSEMBLY
Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.
ADJUSTMENT AND SELECTION OF ADJUSTING WASHERS
Differential Side Gear Clearance

Assemble the differential parts if they are disassembled. Refer to RFD-33, "Differential Assembly" .
1. Place differential case straight up so that side gear to be mea-
sured comes upward.
SDIA0817E
Content Conditions and Measures
Hypoid gear

If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.

If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new
drive gear and drive pinion as a set.
Bearing

If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear

If any cracks or damage on the surface of the tooth is found, replace.

If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer

If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal

Whenever disassembled, replace.

If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace
them.
Differential case

If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange

If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the
companion flange is found, replace.

2. Using feeler gauge, measure the clearance between side gear
back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.
CAUTION:
To prevent side gear from tilting, insert feeler gauges with
the same thickness from both sides.
3. If the back clearance is outside the specification, use a thicker/
thinner side gear thrust washer to adjust. Refer to RFD-38,
"Side Gear Thrust Washer" .
CAUTION:
Select a side gear thrust washer for right and left individu-
ally.
Side Bearing Preload

Selecting carrier side bearing adjusting washers is required for successful completion of this procedure.
1. Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.
2. Place the differential case, with side bearings and bearing races
installed, into gear carrier.
3. Insert left and right original side bearing adjusting washers in
place between side bearings and gear carrier.Side gear back clearance specification:
0.2 mm (0.008 in) or less.
(Each gear should rotate smoothly without excessive
resistance during differential motion.)
When the back clearance is large:
Use a thicker thrust washer.
When the back clearance is small:
Use a thinner thrust washer.
