CLK W208 Noisey Diff

[a1sas]

I've got an annoying noise coming from the diff. I would describe the noise as similar to a pad rubbing on a disc. Others have described it as an airflow kind of noise and another said it sounded like a cistern filling up!!!!
All of which are fair comments as that's what it sounds like...
I took it to a guy who put it on a 4 poster lift and listened to it with a stethoscope whilst it was running and he pinpointed it to a pinion bearing in the diff.
Can these pinion bearings be replaced?
My car has only done 60K and is ten years old.
Has anyone had the same problem?
I can get another diff from another CLK that is the same year and done 39K but who's to say that diff wont be the same...

Cheers Guy's

It may be the driveshafts, you would have to take a good look at it (or a mechanic), diff's tend to whine, or make loud distinctive noises
