Q: How do you remove the upper control arm on Mercury Grand Marquis?
A: One way to take off the upper control arm is to loosen the hubcap nuts, lift the vehicle, and detach the wheel. For models 1988-1991, take out the cotter pin and release the stud nut. Use a jack to lift slightly the lower control arm and strike on the Steering Knuckle near the ball joint stud to loosen it. In case of need, use a ball joint stud separator. Remove the nut and pivot shaft attaching bolts then remove the upper control arm. For models 1992-2002, raise the lower control arm with a jack, get rid of the pinch bolt and nut, and disconnect ball joint stud. Take off the upper control arm retaining bolts and assembly. On models for 2003 and up, first, remove the Shock Absorber/coil spring assembly together with harness retainers then remove the upper control arm mounting bolts. When installing put the upper control arm pivot shaft in its position on frame, put the ball joint stud into the steering knuckle, and secure it there.
