Looks like i broke either the transfer case or something in the front axle, maybe a CV joint. I took the front driveshaft out and the noise went away for about a week, now its back and getting worse. So i will be pulling the front axle out and looking for a 2wd 4l80 trans or maybe a th400/th350 to swap in. The suburban is coming along with its tune so i can start getting this thing running like it should.
