Total Preload Torque
1. Remove the side flanges if necessary. Refer to
DLN-247, "Removal and Installation"
.
CAUTION:
The side flanges must removed in order to measure total preload torque.
2. Rotate the drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
3. Rotate the drive pinion at least 20 times to check for smooth operation of the bearings.
4. Measure the total preload torque using Tool.
NOTE:
Total preload torque = Drive pinion bearing preload torque +
Side bearing preload torque
• If the measured value is out of the specification, check and adjust each part. Adjust the drive pinion
bearing preload torque first, then adjust the side bearing preload torque.
CAUTION:
Select a side bearing adjusting washer for right and left individually.

On drive pinion bearings: Replace the collapsible spacer.
On side bearings:
Use thinner side bearing adjusting washers by the same
amount on each side. Refer to
