When driving and get to about 15 mph, I start hearing a roaring type sound from front end. The sound is almost like a rubbing sound, but not grinding. If I'm driving and press the clutch in or move the gear shifter to neutral the sound immediately goes away. There is no sound while idling.

I'm guessing it has to do with a bearing with the transmission or clutch. Any clue what I could be?

As the noise goes away when you press the clutch I would think it is a bearing inside the transmission. Likely on an output or carrier shaft as you say it doesn't make noise in neutral or at idle. The only way to be sure though would be to remove the transmission and pull it apart as there isn't really any way to look inside the transmission with it assembled.

Thanks Steve. I was assuming it was something of that caliber. Time to bite the bullet and take her in.

Appreciate the information.
