1 piece drive shaft problems

hi everyone, names jay i have an extended cab short box 2001 f350 7.3 diesel single wheel 4x4. i have owned the truck for a year and i have now gone through 2 rebuilt driveshafts (1 piece). the truck is used for towing it has a wheel lift under the back... 4 extra leafs and air ride front and back.

i have two problems: 1) i keep having is the annoying vibration between acceleration and deceleration. 2) the H brace joint in the front of the driveshaft keeps wearing away, which i think is causing my problem 1. both time i have rebuilt the shaft it has worn away along with teh driveshafts within 3 months.

my question to all you seasoned powerstroke guys is how do i fix this driveshaft problem? do i shim the driveshaft? could my angle be out of wack because of the extreme driveline angle changes when a car is on the back or not? can i make the shaft more heavy duty? possiblity of mounts causing premature wear?

Thanks again for any help... just getting super frustrated with this problem...

The reason for a 2 piece drive shaft is so that you don't bust parts and wear out the driveline etc when you put weight on the truck and the truck flexes.
