Common Problems This Part Can Address

  • Clicking or popping from a worn rear CV joint
  • Vibration during acceleration from a damaged axle shaft
  • Torn or leaking axle boot conditions
  • Excessive driveline play at the rear left position
  • Noise caused by spline or joint wear on the Cadillac ATS or CTS

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.
