Total Preload Torque

WARNING: This page is about a different car, the 2005 Infiniti FX45 and 2005 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.

Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
Measure total preload with preload gauge.
1. Tool number: ST3127S000 (J-25765-A)
2. Total preload torque (With oil seal):
  1. 1.56 - 2.65 N.m (0.16 - 0.27 kg-m, 14 - 23 in-lb)
NOTE: Total preload torque = Pinion bearing torque + Side bearing 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.
1. When the preload torque is large
  1. On pinion bearings: Decrease the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness. Refer to " DRIVE PINION BEARING ADJUSTING WASHER " and " DRIVE PINION ADJUSTING WASHER ".
  2. On side bearings: Increase the side bearing adjusting shim thickness. Refer to " SIDE BEARING ADJUSTING SHIM ".
2. When the preload torque is small
  1. On pinion bearings: Increase the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness. Refer to " DRIVE PINION BEARING ADJUSTING WASHER " and " DRIVE PINION ADJUSTING WASHER ".
  2. On side bearings: Decrease the side bearing adjusting shim thickness. Refer to " SIDE BEARING ADJUSTING SHIM ".
