Just noticed this weekend that my 4x4 control switch pulls straight out, just like the light switch does when in positions other than OFF ... I read through the 4x4 section of the manual, but it mentions nothing that I saw of what function(s) pull the switch out might enable/disable. The switch in my 2010 F150 didn't pull out ... nor does the switch on my wife's 2012 KR Expedition.

Does anyone know?

You have the electronic locking differential.
You should see a light appear on your dash when you pull that *** out in any mode.
This locks the rear diff.

 

Thanks, kper! Interesting no mention of it in the manual ... nor any of the supplementals.

I hate the location of that switch its directly behind the gear shift lever and ALWAYS blocked with the truck in drive.

 

Page 19 has the symbol and page 277 discusses it.
BTW - it only works up to 25 MPH and then will auto disengage.

 

And in poor traction, it is the best way to make absolute certain that you get power to at least three wheels. With a limited slip, I often got stuck with 1 wheel drive even in 4 x4.

 

Easy to forgot this gem of a feature and worth every penny spent on it. I use it going up washboard roads where the rear fishtails, fixes that everytime. In the snow, I turned the locker on instead of engaging the front axle, wow just 2 real 2 wheel drive worked good. Alas winter is half way here and so it may be time to dust off the **** and start pulling it again

 

I usually go 4x4H first for muddy roads (little snow down here) but you've got that right; great addition and it works when needed.

 

Appreciate the good information, fellas.

honestly I haven't noticed a difference engaging it or not. IMO if it was on the front wheels we would really have something, but locking the front axle would require alot of personal responsibility.

 

Get in a gravel or dirt area, engage the locking diff, turn tight circles. If you don't notice it then, it isn't working.

 

It's fun in a snow covered parking lot in 4 low (when the rear locker won't disengage). Donuts galore!

 

What's snow?
