I searched some of the forums but not sure if this was addressed or if it's even a problem. I just traded in my 97ti and got a sweet 00 323i with 45K. At highway speeds (70-80mph), I was pushing down the gas and I heard a rumble coming from the rear. I'm not sure if that is a normal exhaust noise or there is something going on with the rear suspension. It only happens at these speeds with the gas being pushed. The car is a FL car so I can't imagine anything is rusted.

Thanks for any tips!

I had the same problem around the same mileage but at much lower speeds, 3mph and up, the dealer told me it was the tires. I didn't believe them, I thought it was the Diff. Went to my tire dealer and got a second opinion, he felt it was the tires too. The Conties weren't worn out by any means, but were starting to get down there, and simply got noisy.

After replacing them, (with Bridgestone Blizzaks for winter!!) the car is now smooth and quiet again.

You may want to have it checked though before forking out $$$$$, a good mechanic should be able to pinpoint it without spending a whole lot.

Good luck.
