To remove the control arm, start by loosening the wheel lug nuts on the side to be disassembled and raising the front of the vehicle. Support it securely on jackstands and remove the wheel. Then, remove the control arm balljoint nut, making sure to hold the stud with a wrench if it turns while loosening the nut. Push the lower control arm down until the balljoint releases from the knuckle. If the stud sticks, use a balljoint separator to force the components apart. Next, remove the control arm front pivot bolt and the rear bushing bracket bolts to detach the control arm from the subframe. Inspect the control arm for distortion and the bushings for wear, replacing any necessary parts. Do not attempt to straighten a bent control arm. For installation, reverse the removal steps. When installing the control arm, leave the control arm-to-subframe bolts finger tight until the balljoint has been connected to the steering knuckle. Tighten the balljoint nut to the specified torque. Raise the outer end of the control arm with a floor jack to simulate normal ride height, then tighten the control arm-to-subframe fasteners to the specified torque. Finally, it is recommended to have the front wheel alignment checked and adjusted if necessary after completing the job.
