Thanks for all the suggestions guys. I took the car completely apart last night and am going to put it back together tonight. The only thing I've found wrong so far is my left front cvd was binding a little. I'm going to put the hardened universals from the old car in the front since they will be stronger and don't bind as much at extreme angles. I still have to inspect my hinge pins closely although all my arm are pivoting freely. Also, I will rebuild the diff and try to balance the car after it is all back together.
