I got in the car this morning, it was FREEZING cold could hardly open the
doors as they were all frozen up... Anyway And as I drove off, I heard, what
could only be described as a sound like you've driven over a few stones.. It
was only a quiet noise, and seems to be coming from the back. After driving
for about five minutes or so the noise disappeared completely and now it's
back to normal.. It only does it when the car is moving.. and not when
stationary..

The sound was almost like a watery sound too, was something simply
defrosting, the car had been stood for 2 days in the cold? Really weird..
not grinding.. or knocking.. nothing like that..

Am I being totally paranoid?!?

Any ideas?
