This one's weird E4oD Tranny
Anyone ever heard of this, I just a 95 E250 knowing the trans was bad, drove it home with a vary bad vibration ( VARY bad ) did some reserch and figured it was the torque coverter, THEN I got under it to find the tail housing broke off 2 inch's from the end and just wobbing on the shaft and the tail housing was brand new/recently replaced and I found out that the org. one had also broken, the tranny shifted fine on the 20 mile ride home and I could make the vib go away with the right throttle/load. Would the torque converter "shutter that is common to these Trannys( e4od ) be bad enough to cause this or should I be looking at the drive shaft balance or is there something internal that can cause enough vib to cause this breakage, any help would be greatley appreciated
BTW,it's got 190k, the fluid is good and clean/proper level

Wow. I am no tranny expert and am guessing here.
I doubt the torque shudder is the problem since it is relatively mild. It should take a lot of stress to break a tail shaft. I would guess several things, the engine/transmission mounts are broken, the tranny is misaligned to the drive train, the driveshaft is way out of whack or balance, the driveshaft carrier is shot, your truck is jacked up way too high and the driveshaft is not inline with the tranny, the rear axle is not aligned.
Whatever it is, it is very rare from what I have read.
Good Luck,

I broke a 4x4 "tailshaft housing." Truthfully I think it was because the 12mm 12pt bolts on the driveshaft flange had backed off (ALWAYS loc-tite these!) and so there was a ton of slop in the rear d/s, the torque of low range did not help matters either.
Sorry, that's the most help I can offer, you may not even have the companion flanges but rather just a conventional yoke?

Thanks for the help guys, I think I'm going to get the driveshaft balance checked, I'll have to get a new yoke as this one is now pretty ruff where it rides in the tailhousing bushing and go from there, I'll let you know what I find
