Good grief I am so confused by my bookmarks, nevermind.

Spicer 760 is the way to go.

Wheels can be on and vehicle on ground. Just reach in there and grab the ears of the axle shaft and try to move them.

I checked my axle u-joints and they have no play at all.

The Jeep was on the ground with the wheels straight and i tried to move the yolk as hard as i possibly could but nope. They did NOT move the least bit.

I also re-greased all the joints and no changes.

The wheel is still jerky as it starightens out.

What do you guys think? Bad u-joint?

I have no idea what else it may be. I cant picture it being anything but the u-joints but they are shaking

Go ahead and change out the u-joints. Sometimes they won't have any play in them but will seized up. If the problem still persists after you change the joints, then you know you have to look elsewhere.

get a friend.

Have that friend drive (roll Jeep slowly using the engine actually) your vehicle forwards then backwards with wheels at full turn while you watch the joints and shafts/yokes.

there could be many reasons your wheel is jerky when straightening out, and you should be able to get a real good look while your friend moves it around.

they will need to turn the wheels all the way in both directions.

I drove almost a year including numerous wheeling trips before I found the hairline crack in a cap on one of my spicer 5-760x.

I personally have done more u-joints than I care to remember on Jeeps. I only buy spicers for my own Jeeps but have to re-re-do (not typo) one on the rear of my t-case this weekend..and I think the spicer box I had said china on it so I may look into a high quality AMERICAN MADE u-joint in the future.

quote for truth, just replaced mine for the same reason, I got five years out of the Napa non greasable ones. went for the presicion greasable through the cap ones from Napa this time. Completely cleared up my jerking wheel. There was no play in the joints but once I was able to move the joint around by hand they felt like all the rollers were square. and were very rusty inside.
