PRECAUTIONS
Revision: 2005 July 2005 FX
PRECAUTIONSPFP:00001
Service Notice or PrecautionsADS00193

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.

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

Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.

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 unit is disassembled.

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

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

Be careful not to damage sliding surfaces and mating surfaces.

When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.

Always use shop paper for cleaning the inside of components.

Avoid using cotton gloves or shop rags to prevent entering of lint.

During assembly, observe the specified tightening torque, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.

FRONT FINAL DRIVE ASSEMBLY
Revision: 2005 July 2005 FX
ASSEMBLY INSPECTION AND ADJUSTMENT

Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
2. Rotate drive pinion at least 20 times to check for smooth opera- tion of the bearing.
3. Measure total preload with preload gauge.
NOTE:
Total preload torque = Pinion bearing torque + Side bearing
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 carrier cover. Refer to FFD-24, "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 : ST3127S000 (J-25765-A)
Total preload torque (With oil seal): 1.56 - 2.65 N·m (0.16 - 0.27 kg-m, 14 - 23 in-lb)
SDIA1649E
When the preload torque is largeOn pinion bearings: Decrease the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness. Refer to FFD-40, "
Drive Pinion Bearing
Adjusting Washer" and FFD-40, "Drive Pinion Adjusting Washer" .
On side bearings: Increase the side bearing adjusting shim thickness. Refer to FFD-40,
"Side Bearing Adjusting Shim" .
When the preload torque is small On pinion bearings: Increase the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness. Refer to FFD-40, "
Drive Pinion Bearing
Adjusting Washer" and FFD-40, "Drive Pinion Adjusting Washer" .
On side bearings: Decrease the side bearing adjusting shim thickness. Refer to FFD-40,
"Side Bearing Adjusting Shim" .
Runout limit: 0.05 mm (0.0020 in) or less
