c 320 strange noise

[tanuie]

Hi, I have a 2004 c class coupe facelift, I have just noticed that I
have a clicking sort of noise coming from the rear offside wheel like
one of the wheel bolts being to long, I know this isn't the problem
because I have had it checked. Could it be the drive shaft where it
connects to the wheel ie. uj couplings or whatever, it sounds like
there is something stuck on the inside of the wheel as you can hear it
as it rotates.
Many thanks.

My guess if it only makes a sound as the wheel rotates. may be a screw or a stone in tyre groove or warped disc rubbing pads on rotation ?
