Front end feels like it’s binding up? HELP

[wvfd114]

Replaced the front u joint in my front driveshaft at the axle today went around the block for a text drive. I hardly ever use the four-wheel-drive can’t remember the last time I used it. Engage the four wheel drive in 4 hi and feels like the front end is loading up/ binding and I’m getting tire chirp while driving straight on dry pavement. Put it back in 2 Wheel Drive and there’s kinda a clunk and the front end settles. I’m thinking the front diff is bad? Or the transfer cases Engaging all the way. Truck is a 2009 sport with 192000 miles on it.

I'm going to ask a lot of "duh" questions, but I promise there's method to my madness.

1) Did you grease the u-jount?
2) After reassembling the axle did you check the joint to make sure it moved freely?
3) Is the axle nut properly torqued to spec, or did you just give it the ugga-duggas and hope for the best?
