Here's the deal I was gona go to my sisters house sunday and help them with some plumbing, and then we were gona go take pics of my truck. Here's where it gets interesting. I probably get a mile an a half from my house and I get this terrible vibration at 75mph, I think OH $h!1 I just cashed out the rearend. So I pull over and check the vitals on it (since I've had a slight vibration for the last 2 months), nothin just slack in the backlash(to much). So I limp it back home to find this goodness waiting for me, hopefuly it'll get fixed right this time since I had a driveline shop do the work in 2003.
