Springs will not wear and cause excess camber.

Spec on e53 is up to 2.1 or 2.2° negative camber. It looks broken but is normal.

The ball joints wear out and will cause more than normal camber but more importantly, toe-out condition that will chew up tires very quickly.

You can't tell when under spring tension but you can usually detect some motion in the joint directly behind the hub with a prybar. If it moves any amount it's shot.
