They took the tires off and checked brakes and e brake they said it all looked good.

I would think if it was the brakes when I would hit them it would make a difference it still makes the same noise.

Process of elimination my friend. I'm sure a solution will turn up soon. Keep us posted!!!!!

Hey man. Sorry to hear the shocks didn't solve the problem.

Update: just remember a few people complains about the exhaust knocking on the chassis .
there are a few post everywhere on how to check and solutions.
Good luck
