still doing it..
what its doing (to the best of my explaning skills) is when i turn tightly, in gear, the locker clunks. Like it is ratcheting but really harsly. There is no sound when not in gear, or when goign straight (leading me to the locker) Another note: The first sign of trouble was after leaving a rolling turn, the locker clunked once about 75ft or so down the road, ie. 75ft after going straight.
It also seems to be less harsh in reverse, but still present.
when taking off, the driveshaft turns and binds up, like there is something holding the wheels. It binds up so much the diff actually rotates up (as in axlewrap).
-I have cleaned out/adjusted the brakes.
-I have put it on jackstands and ran the wheels, they are straight (axlewise).
-All the suspension parts are tight (there has never been axlewrap before).
-The gears/locker look to be in excellent condition with no excess backlash (roughly 55* free rotation in the driveshaft), pinion has no up-down/in-out play in it.

I did the rear u-joints about 2weeks prior, but they seem to be working properly.
