Installation Notes
Verify front left fitment by year, model, and axle configuration before installation. Confirm axle nut thread size, hex size, and compressed length against the original part. Because this axle does not include an ABS tone ring, check the vehicle’s original ABS setup before ordering. Use proper torque procedures and follow the vehicle service manual for axle nut staking and final tightening.
