I now have a rattling noise in rear of my 2001 explorer sport. Happens when say at stop sign and give it good shot of gas. its worse if im on a hill and hit the gas peddal any ideas?

loose exhaust, maybe a heat shield, maybe pipe banging agsint something. One of my hangers broke and my tailpipe bangs against the swaybar strut. I took a short piece of fuel line hose, plit it, and wraped it around the strut to provide some cushion, problem band-aided.
