You usually can't check for loose suspension joints when under tension; if you have air suspension you can pull the fuse/s and crack a line to let out the air and then you can check for play.

The easiest test is: wear on inside edge of rear tire. If it happens you have worn ball joint/s. (which can coincidentally increase your camber angle but it's not the cause of worn tires).

Here's a good video where to check for the most likely candidate for inner edge wear on BMW;.

He was able to move the joint even with spring tension, he mentions the lower ball joint aka rose bushing which is the second most likely culprit to cause inner tire wear.

I have the problem on my car and will be replacing the upper control arms and as needed the rose bushing/s. I will post an awr-fix thread when I finally get to that
