Yes th350, new tires (different set from last time out) driveshaft was balanced with new u joints. Pinion angle is at -4 when checked at pinion, last rear was set up at -5. It is weird, I have never had a vibration before the rear broke and damaged transmission. I was hoping someone could say if it was something in the trans that would only do it in high gear. Driveshaft would vibrate in relation to rpm and should do it in any gear, right? It does not care about mph only rpm. Tires would show up at higher mph. Could be tires. Just odd that same vibration with two sets of tires. I guess I will try my other trans and see what happens. Thanks guys.
