My 1996 sc300 has been makinga strange noise lately. it's almost like a "circular" noise if that makes any sense, (somewhat difficult to describe) coming from somewhere underneath the car. it starts around 25mph, get's more and more noticeable until 55mph, and after that becomes less noticeable (sometimes i have the feeling that it's happening so fast that i just think it's not going on, but still is). I have no idea what this is. might it be the driveshaft? has anyone else had this problem?

Sounds like a resonance problem, which could mean a loose exhaust bracket. Jack up your car and start shaking the pipes around under there. If anything is loose or grinding, tighten it and the problem should go away.

I had a problem with my driveshaft, maybe this will help you.

thanks a lot jt51, that seems like it is my problem, "a whirling sound"
