I was crawling around some terrain while my wife filmed. When I looked at the video I was in a bind with my left wheel in the air and that was the only tire spinning, could this be a wheel sensor?

 

When the wheel begins freely spinning, the sensor will detect this compared to the other wheels and apply braking power to the one wheel to regain traction to the other 3 wheels. This is your traction control system. It isn't immediate but relatively quick. You should of seen an amber TC light on your dash when this was happening.

 

I bought new sensors so that could possibly fix it? I hope the three amigos goes with it.

 

If you have the 3 amigos you will need to use an ABS scan tool to read and clear the codes.

I would recommend that before throwing more money at the truck.
