Ok here is my problem, I have a manual 2004 IS300, and there is this annoying sound coming from underneath the car on drivers side.
Here are the details:
The noise only happens when the car is warm.
The noise stops when you push the clutch in just a little bit.
The faster you rev the engine the faster the sound is.
ie. if you are in neutral and you let it idle, the noise is slower, as you rev it higher the noise frequency increases
I took it into the Lexus dealership, and they said this was a known problem on the 2002, and they replaced a part of the clutch, i think they were the bearings, but this did not fix the sound.
Anyone who can help thanks -- Steve B)
