Hub Breaking, driveshaft problem ?

[gdrake426]

I have a 94 f250. The passenger side hub was broke when I bought the truck, I replaced it and it broke again the first time out. I have noticed that the shaft only seems to go 1/2 - 3/4 into the hub. This is when the wheels are straight and on level ground. I am beginning to think that when I flex my truck or turn the wheel it is causing the shaft to pull all the way out of the hub and then jam back in breaking the insides of the hub. My front end is currenlty the twin Ibeam. Anybody else run into this issue or have any ideas on why my shaft does not go fully into the hub? Thanks in advance

Sounds like maybe it has the wrong axle in it. Does the front end sag really bad?

Front end doesn't really seem to sag. I was kinda thinking the same thing though, looks like it needs to be 1/2 an inch to 1 inch longer to fit correctly.
