I have a 95 F-150 ext. cab short box, with a 302.
It has this really annoying rattel coming from underneath the truck.
It only does it when it is in park or neutral. Could it be some sort of air pump? Any help will be appreciated.

 

maybe the Exhaust system a heat Shield some thing like that.

 

A loose catalytic convertor heat shield is a common problem. I also had a problem on my truck with the ceramic inside the convertor being broken and rattling. Crawl underneath and bang on stuff with your hand and see what rattles.

bad muffler bearings, that would be the first thing i would look at.

sounds like my cat shield when i had my cats on. i think it is a heat sheild

 

Muffler bearings? Whats that

A hanger for the exhaust was the culprit for me a while back.

 

a joke

 

Mike the rattling is from the headers. remember when I put the new gaskets on it rattled then but I fixed it on one side? It's just gonna rattle there's nothing wrong with it, just do what I did, turn up the radio. "what rattle?" First the headers were leaking then there were 2 rattles. They had to have checked it when I got that new ehaust put on it. Believe me I wouldn't sell you a ****ty truck. Any questions ask me or just come over, duh!
