too much lift or trans issues?????

[streetsrfer1022]

Ok i have a 1985 K10 Scottsdale on 40" boggers. I have put nearly 16" of lift give or take on the suspension alone. When I lock the hubs in, the truck is binding on something. It can be powered through but thats no good if something is at too much angle. I have also removed the inspection plate and carrier and pulled the pinion out and the pinion bearings both look good. I have jacked it up on stands and spun both wheel with the driveshaft out and it does not do it. but i put the front drivesahft back on and it goes around almost one full revolution and binds one way or the other. since I have ruled out the issue coming from a hub or inside the rear or one of the bearings, I guess that only leaves the shaft being at too much angle or the transfer case being messed up.
Any thoughts???? This is killing me here.

gear ratio's match front and rear?`

What do you have for a front shaft? That's a lot of lift.

cv joint maxed out to much angle on the front shaft to use a cv joint

Pics of the driveline angles would help. 12" lift should have been plenty to clear those tires. You may have to go with a F*rd high-pinion Dana 60 front and F*rd NP205 driver drop t-case.
