Fix Your BMW Control Arm with These Quick Steps
The control arm seldom needs repair. However, there are some circumstances that may damage and require you to fix or replace your BMW control arm. When you get into a vehicle accident, the control arm may be bent, forcing you to replace it. Because it is an integral part of your vehicle's front suspension, the arm must be fixed or replaced as soon as possible. In addition, worn-out ball joint and bushings may also require repair or replacement.
Difficulty level: Moderate
Things you'll need:
- Jack and jack stands
- Socket wrench
- Ball joint separator or ball joint press
- Safety glasses
- Protective gloves
Step 1: Before raising your BMW vehicle onto the jack and jack stands, loosen the wheel lug nuts and block the rear wheels. You can block them with a stone and a piece of dimensional lumber or wheel chocks. Make sure the block or chock is placed tightly behind the wheels. Then, raise the vehicle until it is high enough to allow some workspace under it.
Step 2:Take out the loosened lug nuts as well as the wheel.
Step 3:When the vehicle is properly supported and the wheel is taken out, you now have access to your BMW control arm and other front suspension components. Detach the bushing, which connects the sway bar to the control arm. Let the sway bar stay in place. You only need to disconnect it from the control arm.
Step 4:Check if you have two control arms. If you have an upper and a lower arm, you can find the suspension spring mounted in between them. Make sure to support the lower control arm with a jack before removing anything.
Step 5:Detach the lower ball joint that is connected to the arm from the wheel hub and steering knuckle. You can do this by removing the castle nut at the joint's end first. Take out the cotter pin or the pinch bolt as well. Using a ball joint separator or press, remove the ball joint from the steering knuckle.
Step 6:Take out the mounting bolts of the BMW control arm at the vehicle frame. Remove the control arm.
Step 7:Same with the other components, the control arms must be cleaned and lubricated at every oil inspection. To ensure smooth riding experience, use appropriate good-quality products. Next, check all the bushings, bolts, joints, and steering or suspension parts. Make sure each part is clean, greased, and in good condition. Replace any part that is rusted or showing signs of wear.
Step 8:When you are satisfied with the inspection and done with the patch up, reinstall everything in the reverse way it was removed. Mount the control arm and its mounting bolts. Tighten the bolts when all bolts are in their proper position, including the ball joint stud. Attach the ball joint into the steering knuckle as well as the castle nut and sway bar. Torque the ball joint castle nut. Install the cotter pin. Put back the wheel and tire. Mount the same lug nuts and lower the vehicle to the ground. Tighten the lug nuts.
