A: Start by loosening the wheel lug nuts on the side where the control arm is to be removed. To begin, loosen the lug nuts of the wheel that you are disassembling and apply parking brake. You may now lift front part of your vehicle off ground using jacks then take off its wheel. Afterward, pull it out from the Steering Knuckle and pry apart its Ball Joint and then remove pinch bolt that holds balljoint on control arm. Then remove bolts holding control arm to subframe, and finally remove control arm itself. Check control arms for distortion and bushings for wear; replace necessary parts. Do not try an attempt to straighten a bent control arm. If any cracks are found or wear signs are observed in busings, take the entire assembly to your local automotive machine shop where they will have bushings replaced with new ones. As for installing control arm, perform removal procedure in reverse order while ensuring all fasteners are torqued properly. Lower vehicle, install lug nuts and tighten them appropriately according to recommended torque values; lower vehicle body after tightening lug nuts provided above. Finally, check alignment of front wheels again aligning when necessary following this exercise too as advised by some recommendations available at work places like auto repair shops near me.
