Dont get butt hurt. We are trying to help you but you seem to not be listening.

well the angles are dead on and are perfect no binding nothing axle sits stright everything is good just cant understand why it keeps breaking the bolts

[Bigbike]

Are you tightening them down to much' and they bind? They dont need to get super tightened down. Do you have an SYE and rear double carden shaft?

pics of your setup might help

My guess is that you are tightening them too far and stripping the threads in the yoke and cause it to have nothing to hold on to and they are falling out because of that. You really can get them tight enough with a 6" wrench.

HOLY FAWK POST 369. Damn this post is fine

do not believe this one bitttt........

not looking to pick a fight here, but if you were a mechanic you'd be tightening the bolts to torque spec not "as tight as you can" and no one would have had to explain what a yoke was in the first thread......

The only other scenarios that could cause it to keep breaking at the yoke are:

-a crap load of axle wrap, binding the u-joint, blowing it apart.
-a god awful pinion angle.
- driveline isn't centered.
-700 hp

basically for a u-joint to continue to break it needs to be binding at some point.

POST PICTURES!!!! that way we can actually help you.....

Is it possible that when you broke one time, the tabs that hold the u-joint caps in broke off the yoke??? that would cause the shaft to let go, no matter how tight you make those straps..... once again, post a picture.

Other than that there is literally nothing else that could cause the driveshaft to "fall out" on the axle end.

ohhh and just so you know, factory torque spec on those bolts is 14 ft/lbs

this is what i was thinking. look at your old yoke and let us know if the little tabs on the ends are broken off. if so the caps were getting lost and snapping everything

glad you found the problem (your old yoke has something wrong with it), now find what your old yoke problem was.
