On-Vehicle Inspection NDS000FF
Make sure that the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are normal.
WHEEL BEARING INSPECTION

Move wheel hub and bearing assembly in the axial direction by hand. Make sure there is no looseness of
wheel bearing.

FRONT FINAL DRIVE ASSEMBLY
Revision: 2007 April2007 M35/M45
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 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.
34. Side shaft bearing 35. Extension tube retainer 36. Side shaft oil seal
37. Dust sealed 38. Side shaft
A: Oil seal lip
B: Screw hole
Refer to GI-11, "
Components" and the followings for the symbols in the figure.
:Apply gear oil.
:Apply anti-corrosion oil.
:Apply Genuine Silicone RTV or equivalent. Refer to GI-47, "
Recommended Chemical Products and Sealants" .
:Apply Genuine Medium Strength Thread Locking Sealant or equivalent. Refer to GI-47, "
Recommended Chemical
Products and Sealants" .
Tool number A: ST3127S000 (J-25765-A)
Total preload torque:
1.56 - 2.65 N·m (0.16 - 0.27 kg-m, 14 - 23 in-lb)
PDIA0792J
When the preload torque is large
On pinion bearings: Decrease the drive pinion bearing adjusting washer and drive pinion
adjusting washer thickness. Refer to FFD-36, "
Drive Pinion Bearing
Adjusting Washer" and FFD-36, "Drive Pinion Adjusting Washer" .
On side bearings: Increase the side bearing adjusting shim thickness. Refer to FFD-36,
"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-36, "
Drive Pinion Bearing
Adjusting Washer" and FFD-36, "Drive Pinion Adjusting Washer" .
On side bearings: Decrease the side bearing adjusting shim thickness. Refer to FFD-36,
"Side Bearing Adjusting Shim" .
