at my wits end with this front end

[QUOTE=DirtyDozen;580971]I'm sure none of these are the right one... but a couple more ideas anyways...
The front diff/driveline will spin even in 2wd. with the hubs unlocked, just thru the drag and friction and what not through the grease in the hubs, so make sure both of the u-joints out at the steering knuckles are still free and easy moving
I've never owned a 1st gen, but I've also never seen a truck with lockouts where the front driveline spins in 2wd. Thats the whole purpose of the lockout

That's correct. Normally the lockout hubs should completely release the front driveline, so that's probably not the issue. That is also why some people install the freespin hubs from Dynatrac and a couple others on the later trucks, in the hopes they will gain some mpg from removing any possible drag from the driveline caused by the unit bearing hubs. But it doesn't really make any difference.

could pinion angle be off a bit? usually vibrations are only noticeable when starting from a dead stop though. not sure if yours has been lifted but i believe the rule is something like for every inch of lift above stock, a 1/4" drop of the carrier is necessary to maintain the proper angle of the driveline.

its in the wheel(up and down not a side to side wobble).. and in the seat.. haha I didn't manage to get alignment done yet, but the radiator emptied out on the way home and the rear half of my serpentine belt is chewed all up, never ending.. truck is about to end up as parts if I can manage to afford a new one.

Probably needs a new tensioner. I take them off and try to work a little gear lube into the action/spring on those when I do a belt. They wear on the sliding surface of the action, become slightly misaligned causing the belt chewing problem.
