loud rotational noise coming from front-end

My GS400 has developed a loud noise coming from the front-end. It seems associated with the drivetrain, as it doesn't occur at idle/rest. It seems to be coming equally from both sides, so I haven't isolated it yet.

Could it be a bearing problem?

I haven't had a chance to look under the car yet, but I plan to reomve the wheels this weekend. Anything specific I should look for or try?

Thanks for your help,
Pat

Check your hub bearings! My 1999 Lexus GS 300 with 80k Miles appears to have the same problem. Make sure your front tires are balanced and your car is properly aligned. The shop can tell you if any suspension parts are bad.

Good luck,

Ours has what sounds to be a similar problem coming from the front right. Have had alignment done, a few times, had the tires balanced/rotated and one of the tire guys told me one wheel couldn't be balanced, possible warped rim. I had them road force ballanced, and this guy didn't warn me of this condition. Still, the sound remains. It gets faster as you go faster until it becomes a single long hum and as you slow it gets slower. Is this the same as yours? I have heard that it may be the tires, but haven't tried replacing them yet because still have tread left!
