A clunk over bumps, loose steering or uneven front tire wear can mean a worn arm or ball joint. Signs like these alone do not prove the arm is the problem, since a worn tie rod end can feel much the same.
Fits
The 2010-2016 BMW 550i GT xDrive, the 2011-2016 BMW 528i and the 2011-2016 BMW 535i all take this arm, and so do many other BMW models.
