Installation Notes

Verify front right fitment by year, make, model, and drivetrain configuration before installation. Inspect axle seals, hub splines, and surrounding suspension components during replacement. Confirm the axle nut thread size and torque specifications for the vehicle before final assembly. Because this axle does not include an ABS tone ring, use it only where the application does not require one.
