Wow that does seem like a scary task unlike the fronts. I'll definately have to take some caution into this. Worse comes to worse, I'll utilize 2 different jacks to do this and a jack stand. I'll loosen the rear top shock nuts first then jack up one side rear. Since I can actually jack the car up to clearance height; remove the wheel and then use a secondary jack as you say as well under the rear control arm near the shock mount. This way being at a higher point, I can slip out the shock as well space wise. I might go as far as to compress the spring also at this point. I know this is a crazy thing but let me tell you everyone shop wise unless it's an MB repair shop fears for replacing these springs.
