I have a 04 f150 fx4, I engaged the 4x4 Yesterday to pull a stump out of the ground and now I turned the 4x4 high on, the light comes on and off. When I put it back on 2wd it feels like the truck is getting bogged down like 4x4 is partically still on. Anyone heared of this.

 

how big was the stump?

 

It was a bush stump
