Broken stub, axle, and u-joint at the same time????? :duh

I'm sure the welded front diff and 36's had something to do with the breakage, but still????????

From the rust on the u-joint, it looks like it had been busted for a while....
Then how does the load get transferred to break both inner/outer axles.......... :goodfinge

Rust is there cause;
A. I was out mudding and had multiple deep puddles to get back home
B. I washed all the mud/gear oil/grease off everything to see the breakage better.

I pulled the other shaft, figuring with the amount of carnage, it might be effed up and looks completely fine, U-joint and all.

WOW, very impressive. I was noticing the u-joint as well. You could have still done what you did with a broken u-joint, I figure. Regardless, wow.

May I try a conclusion that at least makes sense to me?:toothless

I'm guessing that you first snapped the U-joint and then still had your foot in it when the yokes swung around and caught each other and snapped both shafts.:shrug

Anyways, impressive and unusual carnage for sure.:thumbup

I would say the u-joint broke first, either previously or the day in question, then the outer shaft broke and with everything bound up and the wheels maybe turned to help bind it all, the inner broke.

Thats what I thought, but then the U-joint and/or yokes would have to be pretty beat up in at least one spot to be able to bust both shafts??? I looked em over pretty good thinking the same thing, but could not find anything. I did notice the yoke that busted off the outer looks like it had the yokes pushed outward from the center. Maybe that is what bound it up somehow to break the shafts, just odd it left no marks...........

Since I built this 78 beater, it has seen one snow/ice run that was pretty hard, hammerred down quite a bit, but not very binding.

2 or 3 mild rock crawls. Nothing crazy, but binding up all day long just driving around with that welded front.

and then this mudding run which I did have my foot totally in it and the wheel cocked all the way to one side, but we are talking about a bone stock 351M auto, crappy 205 TC LR, and stock 3.54 gears.

That Brute force joint is supposed to be lifetime warantee, wonder what they will say about that........ :toothless

The outer is a clean break and no way for anything to bind once that breaks. Now the outer/inner could both have been weakened alot before the whole thing finally let loose.

Nice work Ox... I'm excited to see what kind of carnage we can pull off in April.

With the wheel cocked all the way to one side and your foot to the floor, I can see the outer u-joint knuckle wedging in there pretty good for at least a second after the outer axle broke and that would be enough to snap the inner. It is unlikely, like you said, that it would happen all at the same time.

It is surprising to see that happen at all. Now if this was Tod posting, well that is just another story:histerica
