I found, thanks to Ice, a new differential assembly for my '89 TII very cheap.

Question is when I replace my old assembly is there anything else I'm going to need to do......I'm thinking drivetrain rebalancing or anything like that.

 

I say no. After installing new diff, if any vibration encountered, take the driveshaft and turn 90 degrees and retry.

 

Thanks for the idea Turbo, I'll definitely try that if I get vibration......anyone else......^^

 

bump.....
