Detailed Description

Delphi TD338W suspension control arm bushing is engineered for BMW front suspension repair where worn bushings can affect steering feel, alignment stability, and ride quality. The rubber material and press-fit design support a factory-style service approach, while Delphi’s OE-focused dimensional and material analysis helps promote proper fit on the specified BMW 840Ci, 850Ci, 850CSi, 540i, and related models.
