Locking Hubs

[greenmntboy]

Just picked uo a 2011 f250 4 x 4 with shift on the fly four wheel drive. (Not the shifter on the floor) Anyhow dealer told me it didnt matter weather i run the locking hubs in free or lock to make the 4 x 4 work?

I thought if they are in Free mode you cant use 4 x 4?

Yes , the hubs can either be switched to lock or auto. Most people leave them on auto to keep the wear and tear down when not in use, then if you need 4x4 just switch the switch on the dash, or if your doing a lot of 4x4 ing in the mud you can lock the hubs.

I believe locking the front hubs will make both front tires pull correct me if I'm wrong

Yes you are wrong. But a lot of people think this. All the lock position does is over ride the auto hubs that are vacuum activated. This is used if the auto hubs don't work. The diff is an open type. Meaning the tire with the least amount of traction gets the power.

The rear on some of the 2011-2012 have a rear locking diff. I have this and use it more than 4x4.

Auto position is when 4x4 is activated by vacuum. When in lock vacuum is not in play, just the switch and you're in!

Edit: ^ What he said, I posted before reading!

Ya most 4x4's are 2x4's and 2x4's are 1x4's. Locking diff's are great to have. When in 4x4 rear lock off so it can drive smoother and you lose traction just pull that locking rear diff knob and off you go. To bad these SRW trucks didn't come with front and rear posi.
