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-33, "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: 2.85 - 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)

REAR FINAL DRIVE ASSEMBLY
Revision: 2006 December 2006 FX35/FX45
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)

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45
Service Notice or PrecautionsNDS0009O

Do not reuse transfer fluid, once it has been drained.

Check the fluid level or replace the fluid only with the vehicle parked on level ground.

During removal or installation, keep inside of transfer clear of dust or dirt.

Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern.
Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause
longitudinal vibration.

Disassembly should be done in a clean work area, it is preferable to work in dustproof area.

Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.

All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.

Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.

Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.

Gaskets, seals and O-rings should be replaced any time when the transfer is disassembled.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.

Observe the specified torque when assembling.

Clean and flush the parts sufficiently and blow-dry them.

Be careful not to damage sliding surfaces and mating surfaces.

Clean innerparts with lint-free cloth or towels. Do not use cotton work gloves and rags to prevent adhering
fibers.
