Ok guys here is an update. The truck handles incredibly well. I need some of your expertise. I have a decent vibration at 58+ mph (its been this way, nothing to do with the new suspension). I thought it felt like it was coming from a pulley on the motor or a U joint. Both U joints have been replaced and when I rev up the engine its smooth as can be. I also replaced the seal in the back of the trans when I had the drive shaft out. Maybe drive shaft needs balanced, but it's the original and I would think it should be good? Any ideas? I know its a million dollar question, but I thought maybe someone out there had experienced this situation? The thing runs smooth at 55mph. Maybe it just wasn't meant to go that fast. But I cant drive 55! haha

Thanks for the suggestions in advance
