Dorman - OE Solutions Suspension Ball Joint P/N:538-809
Handle the pivoting load in your BMW's front suspension with the Dorman ball joint 538-376, a direct-fit replacement for the 2011-2017 BMW X3 [All] and 2015-2018 BMW X4 [All]. Mounted in the front lower forward position, this joint connects the control arm to the steering knuckle, letting the front wheel pivot for steering while the suspension travels up and down.
If a worn ball joint is behind clunking, wandering steering, or uneven front tire wear, this replaces it. A ball-joint press is normally required for installation. Sold individually — each listed vehicle uses two, so order accordingly and replace them as a pair for balanced steering.
