If I am driving the car and get off the gas fast I get a clunk from the rear of the car, it also does the same noise if I stab the gas. It does it real bad sometimes if I am in gear and at a roll slowing down, almost feels like someone chugging a car that can't drive a stick. I have a alum driveshaft and southside lift bars that I am taking off soon because they alsoi make a ton of noise??
