I'm a bit confused now: in some other article I read that the most probable cause for "sweaky" suspension is worn upper ball joint. With a description how to remove them similar to the one Shawn wrote. So what should you replace, the bushing or the ball joint? When changing the bushings, after install you have to secure the bushings with spot welds to prevent them from turning (according to the Bentley). I don't have welding equipment, so how bad is it when you don't do this?
