Step 1: Preparing the Vehicle
1.1. Safely Position the Car
Lift the car using a car jack and secure it with safety stands. Make sure the vehicle is stable and there is no risk of it tipping over. Remove the wheel to access the control arm ball joint.
1.2. Locate the Control Arm Ball Joint
Find the control arm ball joint, which is located at the end of the control arm and connects it to the wheel hub. It might be covered in dirt or rust, so using penetrating oil can help ease the work.
Step 2: Removing the Old Control Arm Ball Joint

2.2. Remove the Control Arm Ball Joint with a Puller
Attach the ball joint puller and carefully, but firmly, start removing the ball joint. If the ball joint is tightly fitted, you can use a rubber mallet to help loosen it. Be careful not to damage other suspension parts.
Step 3: Installing the New Control Arm Ball Joint

Place the new control arm ball joint in the appropriate position on the control arm and gently press it in. Make sure it is well-seated and there are no looseness.
3.3. Secure with Bolts
Tighten the bolts securing the control arm ball joint using a wrench. Ensure they are properly tightened but avoid overtightening to prevent damaging the threads.
Step 4: Inspection and Finishing Up

Before mounting the wheel, ensure that the control arm ball joint is correctly installed and all bolts are securely tightened. Check for any looseness or irregularities.
4.2. Mount the Wheel and Lower the Car
Reattach the wheel to the car and make sure all the bolts are properly tightened. Carefully lower the car from the jack and remove the safety stands.
4.3. Test Drive the Car
After completing the work, take a short test drive to ensure everything is functioning correctly. Pay attention to any unusual noises or suspension behavior while driving. If everything is fine, it means the control arm ball joint replacement was done correctly.
