The rear E-Locker locks the rear differential so both rear wheels spin at the same rate. it can only be used in an off road condition or if you were to get stuck in snow and makes a huge difference. It only engages when your moving below 20 mph and you engage it by pushing the button in the center of the drive mode **** if your truck is equipped with it. I believe it is an option on every trim level not sure if it’s a standard feature on any trim level other than the Raptor or FX4

 

I don't have that option. My **** looks like it should be a button, but its not. Thanks.

 

I'm not sure if it's the same on the 21+, but through 2020, to be clear, you pulled the **** to lock the rear diff

 

It’s a PUSH button on my 2021

 

Leave it to Ford to invert those things. It's like my 19 F150 and 20 Explorer have the folding window buttons in different corners around the exact same mirror control switch. Why Ford, why can't you be consistent?

It also seems wrong to me that it would be push, seems like the kind of thing that you wouldn't want to be able to easily accidentally push with a knee when moving around or something. But, I'm no ergonomcist (yes I made that up)

 

It won’t engage unless your going under 20mph and disengages at 25mph it is recessed into the **** a bit and It seems to be in a spot where it’s not likely to hit with my knee at least with the center console option

 

I'm 6 foot 3 barefoot and I don't think it would be possible for me to get a knee to it.

Does make you wonder about the trucks with a center seat in the front though.
