I wasnt clear on the "hubs are locking in"
Does it work when you lock the hubs manually?

If the front shaft did not turn, doesn't that mean the transfercase isn't shifting? Do you have ESOF or manual transfercase? With a Lariat, i'd assume its ESOF. If so, are the lights coming on when you turn the ignition on? If not, the issue is with your shift motor. If the lights are working, and they shift correctly, I would suspect a bad ESOF relay. There are two ESOF relays in their own box, driver side fender mounted, right next to the brake reservoir. Often times they have been found mounted upside down and the box lid fills up with water and submerges the relays. One shifts the transfercase into 4x4, the other shifts it out. The one that shifts in kinda sounds like it could be your issue. Sorry if I repeated anything you already knew, I explained it in such a way that someone who has no idea can understand it.

Not gonna lie that was pretty hard to read without some pauses put in there lol.

But sounds like to me that your transfer case isn't shifting in and working properly. Try getting under there and tapping on the side of the transfer case. A lot of times this helps to free it up if it hasn't been used in awhile, just be careful when doing it.

Personally if I was you id lift the whole truck off the ground so you can really tell what is going on with ease instead of trying to do it on the ground. If your hubs work, and its not an electrical problem, then the only thing left is the transfer case itself.

I checked the relays with a multimeter and both the ohm reading checks out and the beep test checks out on them. The only thing I can think of now is that the shift motor isn't working.

I don't have a way of getting the truck completely off the ground.

I have been using the 4x4 all the time due to this terrible winter were having, so IDK if it's stuck or not... I'll try tapping on it and see if it's sticking.

Btw everyone I'm his son. I helped him and it turned out to be up in the hub. We listened to the shift motor up on the transfer case and it was actuating just fine. So I figured I would check the front axles and just happened to stumble across the passenger side one not locking in when the hub was locked in.

Thanks for all your help!
