well some of you may remember that thread i started about a loud vibrating sound that I thought was coming from my tranny and that clunking sound that happened when I started off. Well it got worse and the car was lurching and jerking real bad while it was in gear and I was not applying gas. I targeted it down to the first part of the drive shaft. It is real loose and virbating real bad. I hope ther is nothing wrong with my center diff. Anyone had this happen or know what caused it?
