Sway Bar Bushing Replacement, Any Danger?

[zeronero]

Hi, I'm about to replace the bushings that connect the rear sway bar to the frame on my '92 400E, it seems as if it's a straight foward procedure. I'm just wondering if there's a possibility of the bar violently popping out of place when I loosen the bolts to the mounts since the bar is under pressure. I don't know if placing the car on jack stands vs. ramps is better since the bar might then be under a different force with no weight on the wheels. If anyone has experience doing this what do you suggest?

On a side note I'm doing the because my left rear suspension has a squeak coming from it that seems to suggest a bushing, hopefully this one. But more recently another squeak has developed that is related to the cars movement and speed. I reviewed pasts posts and don't think that it's the bearing since the sound is a very high pitched squeak. The brakes are less than 6 months old so that shouldn't be the issue either. Any thoughts?
