Installation Notes and Tips

Verify the front left lower rearward position before installation and confirm vehicle production date on 2005 760i and 760Li models. Because this control arm is not adjustable, proper installation and a professional alignment are important after replacement. Inspect adjacent suspension components for wear before completing the repair.
