DIAGNOSIS

STEP 1. Check if the propeller shaft flange yoke and rear differential connecting nuts and the center bearing mounting nuts are loose.
Propeller shaft flange yoke and rear differential connecting nuts tightening torque: 54 ± 5 Nm (40 ± 4 ft-lb)
Center bearing mounting nuts tightening torque: 41 ± 5 Nm (30 ± 3 ft-lb)

Q: Are the connecting nuts and mounting nuts tightened to the specified torque?
YES: Go to Step 2.
NO: Tighten the connecting nuts and mounting nuts to the specified torque. Then go to Step 3.

STEP 2. Check the sleeve yoke's spline of front propeller shaft for wear.

Q: Is wear apparent?
YES: Replace the propeller shaft. Then go to Step 3.
NO: Go to Step 3.

STEP 3. Retest the system.

Q: Is the abnormal noise eliminated?
