| Vibration
I have been getting a vibration/rattle sound coming from the driver front area.
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? |

THe heat shield behind you that is the one visible from the outside on the exhaust near the exit did this to me on both '02's. It was replace with a different mounting system in '04 by the dealer and this annoying noise stopped. |

Thanks Marco,
I had the heatshield update a couple of years ago.
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. |

Check out the hangers for the exhaust. 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. |
