I am going through the rear in my 1996 2500 now. I read that the Dana 60 and 70 should get new bearing every 100K miles! The rear in the 96 I bought new was shot at 85K miles when I traded it in. Seems the 96 2500 I have now has a Dana 60 being a 5.9 gas engine. I just got a rear out of a 94 V10 automatic truck and it seems to be the same. The 92 rear I took apart was a Dana 70 as it was a Cummins truck. Took apart a perfectly good rear before I realized it wasn't going to work.
