Common Issues This Part Can Address

Installation Notes and Tips

Verify that the vehicle is a 2004-2010 BMW X3 without Sport Suspension before ordering. This assembly uses a bolt upper mount and inset lower mount, so confirm the mounting style on the vehicle before installation. A professional alignment is recommended after suspension replacement to help maintain proper steering and tire wear. Part number 920399 should be matched to the front left position only.

The 920399 assembly uses a fixed-damping design, Q235B housing material, and a protective dust shield to support consistent operation in the intended BMW X3 front suspension application.
