Firebird noise

**Motomas** · 08-01-2009, 04:01 PM

I was driving my firebird today and i hit a big bump then something vibrated under the center concern like underneath the car. Has anyone else had this problem and know what it is? Thank You

If you bottomed out or scraped a little, it could be the piece under the transmission, I did that once in my '98. I would here a rattle once in a while, it turned out I bent that piece up and it was sometimes hitting my exhaust pipe. I had gone over a big speed bump to do it. It sounded like in the middle, underneath.

See if you can possibly get it on a lift or even some ramps...check underneath as it could possibly be something hitting around your tunnel brace or close to it.

Is it vibrating when you hit bumps in the road? with your rpm's? or your speed?

If it isn't making the noise anymore, haven't noticed any performance changes and can't find any damage.... look up to the sky and whisper... thank you.

It could be many number of things. Usually the over the axle exhaust is smacking the heat shield.
