So I've been having issues with my car making a weird rubbing/grinding noise when I accelerate. I figured it was the driver side axle so I replaced it. (It fixed my vibration problem I had and drives soo much better now.) But im still getting that noise! When I was installing the new one I realized the shaft inside the trans had some play in it up/down/ side to side/ in, out etc. Is this normal? Or could this be the source of my noise? If so, is it a serious, costly problem? Thanx for the help!!
