Total Preload Torque
WARNING: This page is about a different car, the 2006 Infiniti QX56. 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.
Tool number : ST3127S000 (J-25765-A)
Total preload (with oil seal):
2.98 - 4.76 N.m (0.31 - 0.48 kg-m, 27 - 42 in-lb)
- 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.
When the preload torque is large
On pinion bearings: Replace the collapsible spacer.
On side bearings: Loosen the side bearing adjust nuts at the same force on each side.
When the preload is small
On pinion bearings: Tighten the drive pinion nut.
On side bearings: Tighten the side bearing adjust nuts at the same force on each side.
- 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.
