Installation Notes and Tips

Verify the OE number 221 330 78 07 and confirm the front right lower rearward position before installation. The recommended special tool part number is V99-1020. Because suspension geometry is affected by control arm replacement, a professional alignment should be performed after installation. Check the paired side reference V30-1869 when servicing both sides of the front suspension.
