i was out yesterday doing some trailriding/desert running, nothing hard. went to crawl off a small ledge and it felt like my brakes were locked. barely got the truck to level ground and had my buddy check out the driveline and the axle was wrapping up as i tried to move. felt like the truck was anchored to the ground. i dropped the rear driveshaft and made it home fine. is something binding in the rear diff?

When I blew up my 12 bolt, I broke the smaller spider gears. One of the gears got lodged between the carrier and the pinion and locked that up. Since it was the smaller spider gears that broke, the big bigger side gears was still in place with the C-clips in place. Now if the side gears are free wheeling without losing the axle-shafts.
It was a one of a million break because if I loose the side gears (with the cross pin still in place) I lose axle-shafts. And I won't have been able to drive home.
I don't think this is your problem because you where able to still get up that ledge. If the pinion was locked like I was, your drive-shafts will not turn at all. Front or rear because they are connected by the transfer case.
Yet the rear end freewheeled home fine.
You got two places to look at, The rear end and transfer case.
Put some jack-stands under your rear axle and see if you can turn the pinion. Probably pull the cover to find any loose chunks of metal that could get lodged and dislodged between the gears.
I would then try to turn the rear output of the transfer-case in all the gears and neutral to see if anything is binding.
BTW, what transfer-case are you running?
Edit, by the year of your truck, I would guess you would have either an auto with a 203, or a manual with 205.

thanks for the tips. 465/205 in the truck with a 12 bolt rear. i was thinking transfer case too but it was rebuilt about 6 months ago. also once i dropped the rear driveshaft i had my buddy look at the back of the transfer case as i drove forward and the yoke is turning fine. i'm thinking it's something in the diff. weird though it happened out of nowhere and with absolutely no abuse. and yeah, without the shaft it freewheels fine, though with a complete driveline everything is locked up.
now if i have to sink some money into the diff, is it worth it on a 12 bolt?

Well, I would still try to find what is wrong before you replace anything. The entire problem could be something else.
Inspect, then replace.
Don't assume and replace.
