Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Total Preload Torque
- Rotate drive pinion back and forth two to three 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 torque using suitable tool (A).
Total preload torque: Refer to "PRELOAD TORQUE "
NOTE: Total preload torque = Drive pinion bearing preload torque + Side bearing preload torque- If the measured value is greater than specification, adjust as necessary.
- Adjust the drive pinion bearing preload torque first, then adjust the total preload torque by selecting side bearing adjusting shims.
- The differential gear case assembly must be removed to adjust the drive pinion bearing preload.
If the preload torque is greater than specification
On drive pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting shims by the same amount to each side. Refer to "DISASSEMBLY AND ASSEMBLY ".
If the preload torque is less than specification
On drive pinion bearings: Tighten the drive pinion nut (only on new assembly).
On side bearings: Use thicker side bearing adjusting shim by the same amount to each side. Refer to "DISASSEMBLY AND ASSEMBLY ".

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
