hey dlyter i really appreciate it if i can find out what it is id be glad to pay the shipping but i have no idea. im thinking something electrical like the torque lock out switch i had a chevy lumina eurosport car that did something similar we un hooked it and it ran great after that. i jacked up the front end spun the driver side no problems smooth as a babys bottom spun the passenger side and found out i have a warped rotor which i knew about but once again it spun freely for the most part with the exception of that warped rotor i also put the 4x4 in nuetral to spin the diferential but that didnt work out to well its the end of the night and i kinda gave up on it i did check to see if there was play back and forth in the 4x4 shaft and there was none however spining it there was some play but couldnt actually spin the shaft didnt have the whole front end off the ground so that will be this weekends project

 

quick update for those of you helping me out im leaning towards electrical and im thinking its the torque converter lock up switch it now does it when your sitting still she was driving it the other day and sitting at a red light she said it felt like someone rear ended her and everyonce in awhile when it hits hard it wont let the truck shift from third to 4th or 2nd to third and then it releases

 

Check wiring for frays/shorts first......

 

There's this and there's that. As far as potential electrical probs go. At least a couple ideas anyway.
