Clicking From Rear Right
 

I'm hearing a really annoying clicking from the rear right that gets louder and faster and I accelerate, on occasion it goes away put not too often. It's like someone put a metal baseball card in my wheel. But when I hit the brakes it goes away. Any ideas before a mechanic rapes me for something I don't need.

some quick suggestions to try atleast:

1)check the rear caliper and see if its loose
2) loose wheel
3) Bad axle ( look for a torn rubber boot on end of axle where it goes into hub or where it goes into the rear diff
4) Loose suspension pieces

Thats all i can come up with right now but atleast its somewhere to start.
