For those that remember Jeff's 3'rd is the charm Diff assembly, there was an issue in that the new axle had a totally different bearing race area that Jeff couldn't figure out. I don't know if he ever did.... but.....
I'm searching around trying to find diff info due to the new 40 issue, and found this thread with this caption and pic:
Finally installed the Detroit this weekend...also found out about the two different axle designs.
Notice the pressed on race and the slightly smaller button on the left axle
Just thought it was interesting and wanted to share....
