A: A special tool is needed to separate the balljoint from the lower control arm. Start by loosening the wheel lug nuts and raising the front of the vehicle on jackstands. Remove the wheel and the engine splash shield. Remove the stabilizer bar brackets to access the lower control arm-to-subframe mounting bolt. Check the bolt for grooves. Hold the bolt while loosening the nut and remove the bolt slowly, noting its placement in the bushing. Remove the shock absorber lower mounting fasteners and the ABS wheel speed sensor harness. Loosen the nut on the balljoint stud and use a balljoint removal tool to disconnect the balljoint from the lower control arm. Remove the balljoint stud nut and pry the knuckle down to separate it from the control arm. Slide out the lower control arm from the subframe bracket. To install, use a new balljoint stud nut and tighten all fasteners. Raise the lower control arm with a floor jack to simulate normal ride height before tightening the lower control arm mounting nut and the lower shock absorber mounting fasteners. Install the wheel, lower the vehicle, and tighten the lug nuts. Finally, have the front end alignment checked and adjusted if necessary.
Q: How to Remove and Install an Upper Control Arm?
A: A special tool is needed to separate the balljoint from the Steering Knuckle, which can be found at most auto parts stores. To remove the right upper control arm, move the engine compartment fuse and relay box aside by releasing the tabs and lifting it off its mounting brackets. For the left upper control arm, move the coolant expansion tank aside. Remove the upper fasteners for the Shock Absorber to allow for access to the control arm fasteners. Remove the upper control arm mounting nuts from within the engine compartment. Loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands. Remove the wheel. Remove the ABS wheel speed sensor harness from the frame bracket. Loosen the nut on the upper balljoint stud and disconnect the balljoint from the steering knuckle using a balljoint removal tool. Secure the steering knuckle aside and move the shock absorber outward. Remove the control arm mounting flag bolts and pull the upper arm from its frame brackets. To install, use a new balljoint stud nut and tighten all fasteners. Raise the lower control arm with a floor jack to simulate normal ride height before tightening the upper control arm mounting nuts at the shock tower. Install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts. Finally, have the front end alignment checked and adjusted if necessary.
