Hey guys,

I was driving home from jury duty today and noticed a rattling sound coming from my rear end. I didn't think much of it but the warmer my engine got the louder the rattle became. It happens usually between 2-3k and sounded like my exhaust was loose? I got home and put the car on jack stands and verified that all my bolts were tight. I had my dad rev the engine for me and it sounded like it was coming from the diff itself but the weird thing was I wasn't in gear? It was just in neutral reving between 2-3.5k yet it was rattling pretty bad. Does anyone have any idea what is going on? Also if I should take it in, any recommendations on where I should go?

Thanks guys =]

 

Yeah, I just checked again. Another thing that throws me off is the sound only happens after the car has warmed up

 

Scrape your car lately on any speedbumps. My car rattles from time to time in that rpm range because of my cat converter heat shield is bent or something, and rattles against the cat... Always does it when the car is warm.

 

I know it has already been mentioned, but I had a loose spare tire bolt that was driving me crazy. I was sure the car was falling apart... Give it a good crank and make sure it is really tight.
