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.
