4wd help
put the truck in park, flipped the switch in the cab to 4H, got out, locked the hubs…
traveled about 12 miles, got in a parking lot, turned the wheel and the truck began to sputter. It really felt like a caliper was sticking and the truck was lagging but I’m sure it was not a caliper. It felt like it was moving forward against some sort of resistance. I heard a slight grind, if I would have gave it some gas I feel like something would have snapped?
put it in park immediately, back to 2wd, unlocked the hubs. When I put it back in drive it did not move.. gave it some gas and it moved perfectly fine. So whatever happened caused some sort of resistance to where the truck would not move forward after putting it in drive and releasing the brake.
For some reason my mechanical mind isn’t putting two and two together. Y’all got any ideas? Where do I even start?
I use it in 4L quite a bit, pulling trailers off road and I never have any issues like this.

Yeah 4wd tends to dislike dry pavement, but probably still will want to have a look at the axle u joints, the stub axle pilot bearings, and the lockouts. Grease and oil never hurt either.

Sounds to me your 4wd is working as it should.
When I drive with my hubs locked I often shift in and out of 4wd as I transition on and off dry road surfaces.
Give the u-joints, hub bearings and hub needle bearings a look and some grease just to be sure there's no other issues.

Don't do this, hard on the system. Only use four wheel drive when wheels can spin independently of each other, especially when turning. Find some gravel, put it back in 4 wheel drive, and test it out. Everything is probably fine.

Sounds normal to me, 4x4 will bind up when turning on dry pavement which requires more throttle input to make it go, then if it's in a bind it won't go back into 2wd until it is released.

+1 for what they all said.
Switch to 2wd when (or before) you have good traction. If your hubs are locked you can do this without stopping, just don't do it while wheels are spinning.
