I think usually the ball joint comes with the forward lower arm. Ironically, was just e-mailing with my shop to see if the ball joints were replaced too this last spring when I had 'em do the arms.

Was also just going to post: Does anyone have a copy (or provide a link) to that really awesome wire frame picture of all of the X5's front suspension components? Actually, the rear too.

I came across that pic yesterday after researching a zillion posts, but now I can't find that one post. This gent's post is needin' the pic too.

Thanks guys!
