A worn ball joint can show up as a clunk over bumps, loose or wandering steering or uneven tire wear. These signs alone do not prove the ball joint is the problem, since a worn control arm bushing can make a similar noise.
Fits
This front lower outer ball joint fits the 1991-1992 BMW 318i, the 1987-1992 BMW 325i and the 1987-1991 BMW 325is, along with many other BMW models.
