2. Remove side flanges.
3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4. Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
5. Measure total preload with the 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.
Drive Gear Runout
1. Remove rear cover. Refer to "Differential Assembly".
2. Fit a dial indicator to the drive gear back face.
3. Rotate the drive gear to measure runout.
 If the runout is outside of the repair limit, check drive gear assem- bly condition; foreign material may be caught between drive gear
and differential case, or differential case or drive gear may be
deformed, etc.
CAUTION:
Replace drive gear and dri ve pinion gear as a set.
