  Q: How to disassemble the control arm?

  A: To disassemble the control arm, start by marking the relationship of the control arm to the front mounting bracket while the vehicle is at normal ride height. Then, loosen the wheel lug nuts, apply the parking brake, and raise the front of the vehicle. Support it securely on jackstands and remove the wheel. Next, remove the stabilizer bar link from the control arm and either remove the Steering Knuckle or separate the balljoint from the steering knuckle. After that, remove the fasteners that attach the control arm to the subframe and separate the control arm from the subframe. For inspection, check the control arm for distortion and the bushings for wear, replacing any worn or damaged parts. Do not attempt to straighten a bent control arm. If the bushings are cracked or show signs of wear, take the control arm to have the bushings replaced. To install the control arm, reverse the removal steps and tighten all fasteners to the proper torque values. Install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the proper torque specifications. Finally, it is recommended to have the front wheel alignment checked and adjusted if necessary after completing this job.
