Well for some reason they would spin and then they wouldn't spin at all

 

I was just reading this, post 17:

Did you try that?

 

Yes i aired down 20 PSIs on all four. It worked like a champ all around on 4hi with the locker off until i got up a hill and stopped to look for a trail that's when it all happened

 

Did you try manual mode like it mentions in that post?

 

No that's i didnt try that

 

Maybe I missed it but can you define stuck for me? As in just all four tires wouldn't move or you were buried to the frame?

If you went into 4lo and the wheels didn't move but they would in 4hi you have a transfer case issue.

If you were buried to the frame and couldn't see the wheels moving well that's a different story.

If you put it in 4lo right now will the truck move?

 

I was about an inch from being buried to the frame from the passenger side and like 4 or 5 inches from the driver side. And they would spin at times but not the whole time i stepped on the gas. Once i was unstuck i put in 4lo and it worked

 

When you say spin, do you mean you pressed the gas and the truck just sat stationary and didn't move and the tires weren't moving at all? What did the engine sound like? Did it rev up or just act like it was bogged down. I have a beach pass and drive on it quite often. The first half of a mile is so loose that people get stuck all the time. My sisters bf almost got stuck in had Silverado last time, but I don't have any problems in 4hi or 4lo. I can even stop and go when others have to keep moving or they will get stuck. My truck is stock and I don't air down the tires (38 psi in them). It will spin the tires and throw sand in 4hi or 4lo. Any of the f150 engines should. I left my parking brake on one time and it acted like what your is doing, but that was an old bronco without a parking brake light. I'm sure this truck would tell you. In 4hi, did you double press the traction control button, just press it once, or hold it for 10 seconds?

 

The truck just sat there revving and the tires would occasionally spin. In 4 hi i pressed the traction control button until it said advancetrac off. I don't think it was the parking brake since i didn't hear the beeping sound it makes when i forget to take it off

 

What works best for the beach? Double press, press once, or hold for 10. Do you feel the truck does better in 4 hi or low? I usually air down to 20. I have a 2015 super crew fx4 with 3.5 ecoboost.
