Rear Shock Replacement - DIY anywhere??

[$chlitz]

i searched and searched, but came up empty...just wondering if anyone knows of an existing DIY for rear shock replacement--NOT air suspension, just standard shocks. i'm thinking it can't be all that difficult, but i really hate just randomly pulling on trim pieces without knowing how they are actually supposed to come off. if i had some sort of basic guide as to what i need to do to get at the top shock mounts, that would sure be helpful. maybe there is another model BMW that is similar? also, my understanding is that the rear shock replacement can be done with the vehicle on the ground, correct? any tips/tricks/guidance anyone can give me before i dive into this project this weekend would be much appreciated! thanks!!
