Short of it is after a few miles sometimes less the Passenger side WARN hub disengages, it partially rotated and very difficult to reset to locked or unlocked when it happens.
History -
This happened with my stock ESOF hubs first went to service them and found Passenger side to be rust ridden and other problems. Due to pricing I went with the WARN Premium hubs (will go back to ESOF eventually).
Put the WARNS on and all was great. Then went on a 130 mile off road trip through the Mohave Desert and last few miles the passenger Hub went out again.
Replace the bearings in the wheel @ stub axle and the stub axle since the blown bearings grooved it out. Plus all the related parts in doing that.
Now test drove new set up for a few miles while locked 4HI, about .5 miles Pavement to get to 2 miles off pavement and back. When I got back the there is tight turn to get into my driveway noticed it was not bucking as expected... SAME hub unlocked itself partially again. Now I am at a loss of what it could be?
Could be the inner axle is being pushed out, pushes the stub axle. I'd drop the front different cover and have a look.... since the bearing doesn't hold the axle into the housing.

I will check that out, my 1st thought was misplaced / out of order thrust washers.

Be glad the hub popped out. I'd disassemble the hub and check the cog in the middle as most by design act as a fuse.
HOLY CRAP!
glad it did "pop" out!
I'll pull everything out and check parts and alignment this week then test drive on a hardpack dirt road this weekend
The customer who owned that tcase had a job that he used 4wd to get to. He left the job and forgot to take it out of 4wd on the blacktop. He made it a few miles and as he was on the long sweeping accelerating right turn entrance ramp and he said he heard a clunk and noticed he had "a leak". He was right, it definitely leaked. Lol. It took a lot to get it out of him to admit that he may of left it in 4x4.
That was a 2001 Excursion 7.3l with 3.73 or 3.55 ratio front and rear. (can't remember which) Luckily I found a used tcase for him and all is good.
Gear ratio between front and back are different. Why you never run dry pavement and try and avoid sharp turns in 4x4.. not much slip.
Gear ratio isn't different between front and back, but wheel-speed between ALL of the wheels is as soon as you start to turn. If you're not on a surface that allows tires to slip some then you'll get the binding
Actually they are..... 3.55 and 3.56 last time I checked and they should be, so the front pulls. Going down the road, they will bind, not just in turns.
I'll double check.
Edit. My F150 was that ratio, this truck is 3.73. But I would suspect the same. If they were the same ratio, driving in dry pavement would not be a big deal.
