To me it sounds like a manifold/exhaust leak. It occurs during light acceleration when climbing a grade. I have questioned it a few times at the dealer but they say the manifold is fine. It seems to be getting worse. The heat shields seem tight. Any ideas what this could be? | ||

It was replace with a different mounting system in '04 by the dealer and this annoying noise stopped. | ||

I checked the shields - looks ok. How about the joint where the manifold meets the muffler or the manifold gasket? Has this been a weak area? Do the dealers have a way of pressure testing exhaust systems to find leaks? Also, the problem was most evident climbing elevations at slow speed at roughly 10,000 feet. | ||

I had a hanger that holds it in place break and it was essentially rattling near where it was supposed to be, but broken for sure. I think someone else with a 2002 has had the hangers break also. | ||
