INSPECTION AFTER DISASSEMBLY
Shaft
Check shaft for runout, cracks, or other damage. Replace if there are.
Joint Sub-Assembly (Wheel Side)
Check the following:
Joint sub-assembly for rough rotation and excessive axial looseness.
The inside of the joint sub-assembly for entry of foreign material.
Joint sub-assembly for compression scars, cracks, and fractures inside of joint sub-assembly.
Replace joint sub-assembly if there are any non-standard conditions of components.
Housing and Spider assembly (Front Final Drive side)
Replace housing and spider assembly if there is scratching or wear of housing roller contact surface or spider
roller contact surface.
NOTE:

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: 2006 January2006 M35/M45
Concept of Auto Active Test
IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN commu-
nication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.
If any of systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

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.
