  3. Remove the front wheel.w211_e320_e500_front_control_arm_diy_55
  4. Remove the wheel speed sensor from the steering knuckle. All you need to do is remove the bolt on the sensor and unclip the wire from the plastic holder.
  5. Next, we must remove the bolt on the top of the ball joint. Before you do so, support the control arm underneath using a jack. A transmission jack is ideal in this situation. You will need to push the control arm up. w211_e320_e500_front_control_arm_diy_24
  6. Press out the old ball joint. Once you remove the bolt and move the control arm out of the way, you can press the old ball joint out. To get help pressing the ball joint out, see the video below. w211_e320_e500_front_control_arm_diy_64
