I recently noticed a vibration that felt like a bad u-joint. I replaced both u-joints and the vibratio has seemed to stop but now I hhear a rubbing sound at tip in (foot barely on the gas) but stops when more throttle is applied. It also does it when slowing down to stop. I checked the tranny mount its tight and I pulled off the inspection plate on the tranny and I didn't see anything wrong. So my question is, what does this sound like that could be causing the problem?
