I've recently done my 85 380se's bearings. The hardest part was realizing that I needed something more solid than a screwdriver to drive out the races from the hub. Once I found my trusty socket extension, the task was pretty easy.
I removed the grease caps with a pair of channel locks. Wasn't too worried about damaging them, as new ones come in the bearing kit. Getting the new ones on was a pain until I realized that I was working against the hydraulic pressure of the grease from the cap being over filled.
