Installation Notes and Tips

Verify axle nut thread size, spline count, and overall length against the removed part before installation. This axle does not include an axle nut, and it does not include an ABS tone ring. ABS axles fit non-ABS applications unless otherwise noted by the vehicle listing.

For best results, inspect related suspension and hub components during replacement and confirm the front application matches the vehicle’s drivetrain configuration.
