Common Repair Uses

  • Clicking or popping noises from the rear axle area during turns
  • Vibration or shudder during acceleration
  • Boot damage that has led to grease loss
  • Axle shaft wear affecting rear driveline operation
  • ABS-related service when the tone ring and sensor trigger pattern are part of the repair

Installation Notes

Verify rear left fitment by year, model, and axle configuration before installation. Confirm spline count, inboard bolt pattern, axle nut thread size, and ABS ring style against the original part. Use proper torque procedures and replace any worn mounting or sealing components during service. Because this axle uses a bolt-on inboard connection and a stake-style axle nut, follow the vehicle service manual for removal and installation steps.
