Golf IV R32 :: Making Noise While Angling Out?

Trying to isolate a troubling noise from the back. The ONLY place the car makes this sound is angling out of my driveway, which I always do to avoid scraping. This twists the car along its length, because the last bit of the driveway slopes down into the street beyond, and the street goes uphill to the right. So it's down one angle while heading up another. It's a loud heavy snap/clunk, like something unloading tension. I think.

Have a UNIbrace in place, took it out for a while, no change. Next to investigate is RSB doing something. I'm thinking I should just undo the end links so the bar is not in play... then if that sound is still there I know that's not what's causing it.

But... do I want the weight of the car off the wheels to undo the end links (top bolt that doesn't go through the shocks, of course). Or does it not matter? I don't wanna release tension abruptly (speaking of which) by undoing incorrectly and have something go boing and smack me in the face. OR, I guess the proper way to ask is "What's the correct way to take load OFF the RSB so I can undo the end links?"
