Installation Notes and Tips

Install RK623740 at the front left lower position only on the listed Cadillac XT5 and GMC Acadia applications. After replacement, inspect alignment settings and verify all suspension fasteners are tightened to the vehicle manufacturer’s specifications. Because this assembly includes the ball joint and bushings, it is suited to a full lower control arm replacement rather than a partial repair.
