Where do you hear this noise? Under your ***? Or near the rear end? Could be a few different things.... Torque arm mount, lower control arm bushings.... Have you had it on a lift?

 

under my ***, you know what i didnt even think about the torq arm mount and that makes sense thanks brother

 

No problem, try and get it in the air and look everything in the rear suspension that you can.
