Where does this ball joint mount?
It installs in the front lower rearward position on the listed BMW xDrive models, joining the lower control arm to the steering knuckle.
Will this fit my BMW?
It fits many BMW xDrive models, including the 2013-2019 BMW 650i xDrive Gran Coupe, 2012-2016 BMW 528i xDrive and 2010-2015 BMW 750i xDrive. Check the "Vehicles it fits" section to confirm your exact year and model.
What are the signs of a worn ball joint?
Clunking or knocking from the front suspension, loose or wandering steering, and uneven tire wear can indicate a worn ball joint. Have the cause diagnosed before replacing.
Do I need to replace both sides?
This listing is for one joint. Replacing the matching joint on the other side at the same time helps keep steering balanced and tire wear even, so ordering two is often recommended.
