I replaced my wheel bearings, shocks, and tie rods since then, and the shudder only comes back on certain road surfaces, so it'll take a full rebuild to get rid of it totally.

save some time and spring the bucks to have a mercedes dealership check out the front end. Don't let them fix it, just check it out. Once you find out your issues, decide which ones you can fix yourself. Any that you cannot fix, either go to them or some other knowledgeable shop for the work. Also, be sure to put the car in the air and check the condition of you center-bearing carrier. they are hardly ever checked or changed. The carrier is made out of rubber and they do wear and get raggy over a period of time. Deterioation of this rubber carrier can cause drive shaft vibration.
Hope I have provided some help. Any further questions, give me a shout at:
