Thanks Guys!!!!!!

Put a spool in it and be done, that or go for a 9" or 14 bolt. You are obviously very hard on a third member! Are you setting these up or is a professional doing it?

they are professionaly set up. we can't figure out what is going on. i have snapped two axle shafts as well

Something isn't right. That shouldn't be enough power to do that kind of damage...unless you are neutral bombing it.

no no netural bombs here i did that in high school and learned my lesson.
yea that is the problem we have no idea why this is going on. i am guessing that maybe i will get another old school since they are cheap and try another person setting it up and see what happenes. this is my day to day driver so the spool is out. the eaton that just blew up i bought off e-bay so that may have been the problem there. i just don't know. oh and i am running the 28 spline as well axles

Maybe you housing is damaged!

possible. I would have to put my money on ether the person setting it up, or your driving habbits. Also those 28 spline axles are garbage.

+1 on both those. Upgrade to 31 spline too.

35 spline, they are really not that much more than 31 or 33, and these are heavy trucks.. just my .02 :pow:
