I have a similar problem.

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.
