I blew this tranny some years ago but just today got around to opening it up.
I thought I'd post up some pics of the carnage for you guys and also add a word of caution for all of you running the lockout hubs on your tandem rears.
All this IMO was caused by driving with the lockout hub incorrectly.
with a very rough road----------------------------
what I realized afterward was that when I was running down the interstate the rear axle in my truck kept bouncing (forward is disconnected) and when it would bounce the motor would wind up and shock load the trans and every part of the driveline.
when the main shaft broke it became out of round and also busted the seal carrier on the back of the case.
so it appears that the main shaft in the trans is the weakest point.
A word of caution to guys running rough roads. slow down or step on the clutch if you see the tires bouncing or can see the rpm's jump when you hit the bumps.
I have never noticed this happen with both axles connected bc they cancel each other out and the shock isn't sent to the trans.
Thanks for the info. I have my rear driveshaft removed. My truck sees 99% on road miles. I have not noticed any bouncing so far, but I will keep an eye out on the bumpy roads. Have you tried running the lockouts in the rear axle to see if the bouncing stops?

yes. it's much worse. the suspension design makes the front axle want to raise up when under power. it's much better to have the rear most axle doing the pulling, gives a tighter turn and less tire wear plus more MPG.
Jwaller is absolutly correct, I have long term, high mileage experience with deuces with rear axles disconnected and agree, drive the rear rear axle, not the front rear axle.
