Installation Notes and Tips
Verify front right fitment by year and configuration before installation. Confirm spline counts, axle nut thread size, and compressed length against the removed part. Because this axle does not include an ABS tone ring, match the vehicle’s ABS setup before ordering. Use proper torque procedures and replace any worn related hardware or seals as needed during service.
