Detailed Description
The Westar ST-8992 suspension strut mount is designed for the rear suspension on 2004-2010 BMW X3 models with stud plate only fitment. As the upper attachment point for the strut assembly, the mount plays a direct role in suspension movement, body isolation, and overall ride quality. When this component wears, the vehicle can develop noise, vibration, and less precise suspension control. This part cross-references Monroe Shocks & Struts (e.g., 908992) for the same application. Westar ST-8992 is a direct-fit replacement choice for BMW X3 rear suspension service where the original mount has deteriorated.
Common Problems This Part Can Address
- Clunking or knocking from the rear suspension
- Excess road noise or vibration entering the cabin
- Loose or degraded upper strut support
- Uneven tire wear related to suspension movement
