Hello I have 05 club cab with a noise which seems to be around the rear passenger side. It's like a banging of 2 pipes together. It does this while going at any speed. it seems to be when the truck is on uneven pavement where the body might flex. If I drive over a strip in the road where both wheels hit it at the same time, it is not noticable. It has been on the lift twice and the exhaust is tight and not close to hitting anything. It sounds like an exhaust banging. Would shackles make that kind of noise? They seem to be ok. What is the best way to check them? It has the big tow package if it makes any difference. It can get really loud on these great PA roads and will really clunk at times . Any help is appreciated thank you
