Ok, well, the noise has come and gone, sometimes I wont hear it for weeks, or longer, but then I hear it for days...
It seems to originate on the drivers side rear tire, the car doesn't seem to be affected by it, besides the noise, accelerated/brakes without a problem, I took the tire off, and CV boots were in intact, dont know what else to look for, I've made a small audio file with my cell phone, so please bear with me, you'll have to listen to the entire 44 seconds of audio:

Sounds horrible, did you record this from the drivers seat?
Rear wheel bearing, maybe?
Pull the hub, and inspect the parking brake, sorry, but that's all I've got.
Good luck.
My 240Ds rear half axles are going bad. From a post either here or at mercedesshop.com, someone pointed out the the half axles form a wear pattern from primary forward motion. If you drive in reverse for a short distance, some "resets" and you can get a few more miles before the noise reappears. SO I tried it, it worked for me.
I know the half axles need to be replaced, but this gives me a few months or more to do some other more pressing maintenance - oil cooler lines, aux cooling fan.
God that sounds awful. I would go with the easy fix first and replace the axle. Just find a decent looking one at a yard, its a pretty easy fix and a $30 or so part used. Bearing is PITA.

Yes, while driving, I went to a quiet part of town, and was trying to accelerate so I could give the listener the full aspect of the clank, I was finally able to get the rear drivers side window working, so being able to hear this even worse, was my prize...

triguy84, when in reverse, I hear the noise 95% of the time, but of course since its in slower speeds, its just a clank here and there, but definately clanks, lol, and it doesn't seem to help my forward motion, I wont hear anything for a while, then I'll hit a bump or whatever and hear it all over again, good luck on the oil cooler lines, I did my aux fan a while back, and it was cinch.
that's awful. How fast do you have to go before you can hear this? it sounds like a piece of the parking brake broke off inside or your rear dif is completely shot. anyway, if you put the car on the lift and let it run it shouldn't be hard to locate. good luck
I agree with the wheel bearings being a possibility. Jack the wheel up and see if you can feel any wobble or hear anything.
Rear wheel bearings are one job I'd pay someone to do.

I jacked up the car yesterday, and I couldn't find a thing wrong with it, I thought I was going to see atleast the hub setup as the front wheels, Im thinking I would have to remove the entire caliper and rotor??
I just found a mpeg video I had purchased when I first purchased the car on brakes, and it has a nice tutorial on rotors, pads, and repacking the front bearing(s), the guy switches over to the rear pads/rotors, and doesn't say how to repack them, just says "the rear ones are easier".....

Sometimes as soon as I pull out, sometimes I go weeks, or longer without even hearing a little clink, but you know, funny that you should mention it, I've seen that lately when I do apply the parking brake, it only seemed to "grasp" on one side, I can even feel the car move in a certain direction, I have absolutley no access to any lifts, and any local shop would surely charge me hundreds of $$$ to even diagnose the problem, atleast thats how they act around here (Los Angeles)
