I have a 04 cobra solid axle swap when i floor it i hear a pop kinda like metal pop when i let off it pops and the rear end sways like it popped back in place. it sounds like some thing hitting the body in the rear. i have replaced upper and lower control arms all poly bushings, looked at the torqe boxs cant really see any damage and replaced the whole rear end. any other suggestions or does any one know how ot meaure the torqe boxs for strightness in relation to the body i am out of ideas. :cuss:
