Installation Notes and Tips

Confirm the vehicle position before ordering, since this part is listed for rear applications only. Review the application details for your BMW X3 or BMW X4, including trailing arm notes where shown, before installation. Because bushings, ball joint, and mounting hardware are not included, inspect related suspension components and replace worn mating parts as needed during service. A professional alignment is recommended after rear suspension work.

Quality Assurance

Delphi uses OE-focused engineering, dimensional analysis, and material testing to support fitment and durability. The part is evaluated for temperature extremes below -40 degrees C and above 120 degrees C, and for extended salt spray exposure to help verify corrosion resistance in harsh environments.
