Delphi Suspension Control Arm Bushing P/N:TD4015W
Delphi TD1638W front control arm bushing for the 2017-2020 BMW 230i xDrive and other vehicles cushions the joint where the control arm pivots. The bushing is designed to OE standards.
A worn bushing here can show up as a clunk over bumps, loose-feeling steering or uneven tire wear. Ball joints, tie rod ends, struts and the control arm itself can be behind those signs too, so find the cause before buying. These cars take two bushings, one on each side of the front axle.
This front control arm bushing also fits the 2017-2020 BMW 430i xDrive and the 2017-2020 BMW 430i xDrive Gran Coupe, among many other BMW models. Owners of a different BMW can look up their own car under the "Vehicles it fits" section.
