Hey guys

I have a 94 vr commodore v6 auto. And I've noticed over the last few weeks that as I take of I get a very loud crunching/grinding sound. I can even feel this through both side of the footwell I am not sure what it is. I can hear it even when the front wheels get a large knock like going over a hump or through a ditch.

I have also noticed that when I put my foot down in the morning when I first start her up it is the loudest an it also increases with loudness as the revs get higher.

Hope some one an help fix this

Cheers
