Installation Notes and Tips
Verify the vehicle ID code before ordering, since 2016 Cadillac ATS and CTS listings include AA5T and AA7T notes. Confirm rear left position, spline count, axle nut thread size, and overall length against the original shaft before installation. Inspect the mating hub, seals, and fasteners for wear, and follow factory torque specifications during assembly.
