If the suspension is hanging, you're mostly ok. There will still be a little spring tension left, but you should be able to mitigate that. It would probably be helpful to loosening trailing arm bolts if you remove the spring first, but I'd think you'd get away without it. Just be prepared for parts to move when you disconnect something. It shouldn't be violent unless you have your hands, legs, or face in the wrong place.

Sorry, I read that wrong. Not enough coffee maybe, look at the post time. LOL
