Thanks WOL. I know you've written this before. Even if the rzeppa is stronger, with a lift putting it in a more extreme angle, it will eventually compromise it's strength.

WOL, one more question, so the strength difference between a 1350 and 1310 is in the shaft itself? Are the joints the same or are 1350 joints stronger also? Where exactly is the strength difference between the two?

not exactly - the extreme angle will cause the cv boot to fail prematurely and once that happens, it's just a matter of time before the bearings inside fail.

a 1350 u-joint, it's yokes or flanges, double cardan and shaft itself is literally a lot bigger than those on a 1310. a 1350's shear size difference is where the strength difference is.

Makes sense. Thanks again!

This is exactly what happened to me and the next time I put it in 4wd it made all kinds of noise. Freaked me out until I found the problem. (thanks to research on the forum)
