REAR FINAL DRIVE ASSEMBLY
Revision: 2004 November 2004 FX35/FX45
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)

On-Vehicle Inspection and ServiceAES000MJ
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
Measure axial end play by installing and moving up/down between suspension arm and axle with an iron pry
bar or something similar.
CAUTION:
Be careful not to damage ball joint boot.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace if necessary.
Wheel Alignment InspectionAES000MK
DESCRIPTION
Measure wheel alignment under unladen conditions. “Unladen conditions” mean that fuel, engine coolant, and
lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.
PRELIMINARY CHECK
1. Check tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial end play.
4. Check suspension arm ball joint axial end play.
5. Check shock absorber operation.
6. Check each mounting part of axle and suspension for looseness and deformation.
7. Check each link, arm and member for cracks, deformation, and other damage.
8. Check vehicle posture.
CAMBER INSPECTION
Measure camber of both right and left wheels with a suitable align-
ment gauge and adjust in accordance with the following procedures.
If outside the standard value, adjust with adjusting bolt in front lower
link.
NOTE:
After adjusting camber, be sure to check toe-in.Axial end play : 0 mm (0 in)
Camber : Refer to RSU-18, "
