When I'm accelerating, my car produces a sound as if a tire is hitting a loose panel. Its like wrruuuunnnng and it only happens when I'm accelerating. When I'm deccelerating, it goes away slowly.

I checked my four tires and the panels look okay. No signs of any problem.

Could this possibly be a muffler issue? Mine is a 97 Jetta.

Any ideas???

Thanks

is it a consistant whir? or is it more of something like the sound of a bad wheel bearing, making a constant clicking, as if you had a rock stuck in the tread of your tire?

does the direction of the wheel effect the sound at all, i.e. is it louder during a left turn?

are the brakes new?

is the sound coming from the wheel well?

Thanks for all the suggestions. You guys got it right however, before I read everyone's responses I checked the rear tires and removed the brake drum. I found out that the inner and outer hub bearings are bad on the driver side. I decided to replace the bearings on both sides for preventive maintenance coz I was told in the past that, if one breaks, the other will follow suit.

Thanks a lot guys.

i used to have a manifold heat sheild vibration when i would first start up my car and would get louder as i accelerated. but once it got heated up, it would go away. i ended up prying up the loose piece of metal and that worked alright...
