Some one help me
 

My 2000 a6 is making a ticking noise (not the engine ) only when im moving it sounds like a marble spinning in a can

Wheel bearings or CV joints most likely.....

It sounds its in traney but shifs fine

I'm going to second the wheel bearing or CV joint diagnosis, and also throw in perhaps even a seized caliper that has gone so long that it's finally worn through the pads and is now pressing the shoes into the rotors.

OK something to add I drove it in the rain to day and it went a way
