Banging Noise
My car is making a loud banging/grinding noise from underneath the car. It gets louder when the rpm's go up, and it goes away when I push the clutch in, and seems to go away when im coasting. What could this be?

If it only makes the noise when the car is moving, it could be a u-joint.
Sounds more like a bearing, though.

Re: Banging Noise
If it does it when the car is not moving, I would focus on the transmission. Any lube in it?
