dantwomey Posted March 1, 2010 Report Share Posted March 1, 2010 For the last couple of months I've had a noticeable rattle at idle that I'd be damned if I could find. At first I thought for sure it was something loose on the exhaust or the exhaust touching the frame. It was loudest at idle and but it wasn't tied to engine rpm. In fact most of the time when I revved the engine it would go away. Well, I crawled underneath at idle and I could hear the noise but I couldn't find anything that wasn't rock solid. No loose parts and nothing touching the frame. But the noise was still there. Well today it got so bad I thought something was going to fall off so I took it into the dealership. Turns out I have a loose piece of metal inside my right side cat. Thinking back to the time I was under the truck that's what it sounded like. I had my face in front of the cat and could hear the noise but couldn't find it. Oh well, I feel better now knowing that nothing important is going to fall off. Live and learn!

dantwomey Posted March 1, 2010 Author Report Share Posted March 1, 2010 I have to pass the dreaded sniffer test and a visual every second year so I can't take that chance. Regards, Dan Quote Link to comment Share on other sites More sharing options...
