Maybe you need one of these from the posi-lock people.

Part No. 100: Cast Iron Fork Heavy-duty, cast iron fork with pads Replaces your old worn out fork and pads on Dodge applications

 

what do you mean by "after 5 miles the 4 wd gives out" ? gives out how ? what all breaks ?

the fork just slides a collar over the 2 piece axle. it shouldn't have any pressure on it at all.
i'd recommend putting the truck up on 4 jack stands, taking the cad assy off, manually sliding the collar and run the truck in 4wd and watch to see what is happening. don't get hurt. if you are breaking forks, something is badly binding or out of alignment.

by the way, are you driving on slippery surfaces or hard dry pavement. dry pavement causes some serious drive line binding when turning. combined with something else, it might be causing a lot of stress
