Detailed Description
Part number 31126758513 is a URO suspension control arm engineered for BMW front suspension service. It restores proper suspension handling and braking stability while maintaining the original control arm geometry needed for accurate alignment. Unlike OE-style rubber-insulated ball joints that are prone to failure, this design uses replaceable full-metal ball joints that can be serviced with standard tools. This part cross-references MOOG RK80531 and Beck/Arnley 102-5394 for the same application.
What It Helps Address
- Front-end looseness or wandering on BMW Z3 and 3 Series models
- Uneven tire wear caused by worn suspension geometry
- Noises from a worn lower control arm ball joint
- Reduced braking stability during suspension movement
- Alignment issues after control arm wear or replacement
