Couldn't find the answer on the forum or in the owners manual.

My previous ford was a 79 F150 so the hubs on my 2006 are a little different.

I took a pick of one of my hubs. Currently as the pic looks is the hub set to auto?





Is the yellow line I circled the line I want for auto hubs? It was actually turned to the other line and I think that's where my noise was coming from when doing some tighter turns.
I'm still learning and I'd rather ask those that know instead of just guessing.

 

That looks like where it should be for auto, but I'm not 100% on that!

 

I'd agree with Pat, that looks like it's in Auto to me. If it was turned to the other line and you were getting noise on tighter turns then I'd definitely say that the other line is the locked position.

Yeah turning it back brought back the noise. Now I know what was causing the not so tight turns and noises.
thanks guys.
