FRONT OIL SEALPFP:38189
Removal and InstallationADS000JP
REMOVAL
1. Remove the rear propeller shaft. Refer to PR-8, "REMOVAL" .
2. Put a matching mark on the end of the drive pinion correspond-
ing to the C position matching mark on the final drive companion
flange.
CAUTION:

For matching mark, use paint. Never damage drive pin-
ion.

The matching mark C on the final drive companion flange
indicates the maximum vertical runout position.
3. Using the drive pinion flange wrench, remove drive pinion lock
nut.
4. Remove the companion flange using the puller.
5. Remove front oil seal using the side bearing outer race puller,
INSTALLATION
1. Apply multi-purpose grease to sealing lips of oil seal. Press front
oil seal into carrier with tool.
NOTE:

When installing the oil seal, be careful not to get it inclined.

Discard the old oil seal. Always replace with new one.

SIDE OIL SEAL
Revision: 2004 November 2004 FX35/FX45
INSTALLATION
1. Apply multi-purpose grease to sealing lips of side oil seal.
2. Using the drift, press-fit side oil seal so that its surface comes
face to face with the end surface of the case.
CAUTION:

When installing the side oil seal be careful not to get it
inclined.

Discard the old side oil seal. Always replace them with
new ones.
3. Install the side flange with the following procedure.
a. Attach the protector to side oil seal.
b. After the side flange is inserted and the serrated part of side
gear has engaged the serrated part of flange, remove the pro-
tector.
c. Put suitable drift on the center of side flange, then drive it until
sound changes.
NOTE:
When installation is completed, driving sound of the side flange
turns into a sound which seems to affect the whole final drive.
4. Confirm that the dimension of the side flange installation (Mea-
surement A) in the illustration comes into the following.
5. Install the drive shaft and axle assembly. Refer to RAX-9,
"REAR DRIVE SHAFT" andRAX-5, "WHEEL HUB" .
6. Align the installing position of the ABS rear wheel sensor. Refer to BRC-57, "
WHEEL SENSORS" . Tool number : KV38100200 (J26233)

COMPANION FLANGE RUNOUT
1. Fit a dial gauge onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate the companion flange to check for runout.
3. Fit a test indicator to the inner side of the companion flange
(socket diameter).
4. Rotate the companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion gear by 90° step,
and search for the point where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c. If the runout value still outside of the limit after the companion flange has been replaced, check pinion
bearing and drive pinion assembly.
TOOTH CONTACT
Check tooth contact. Refer to RFD-24, "TOOTH CONTACT" .
Disassembly and AssemblyADS000JU
REMOVAL OF DIFFERENTIAL CASE ASSEMBLY
1. Using two 45 mm (1.77 in) spacers, mount carrier on tool.
2. For proper reinstallation, paint matching marks on one side of
the bearing cap.
Bearing caps are line-board during manufacture. Replace them
in their proper positions.Runout limit : 0.13 mm (0.0051 in)
