Guys im in North East PA and Ive driven lots of 2wd pickups and vans in snow,,,I havnt driven my new F250 in the snow yet,,,LOL,,,still running my 07 Ranger 4cyl 5sp 2wd even if it does snow,,,just soo used to it,,but it seems to me having a locking rear will i really need to use the 4wd drive that much?????,,,i usually dont even use 4wd unless theres alot of snow or i know im going up hills or something,,,

 

I used the E-locker in snow. Bad idea in my opinion. With the rear axle locked, unequal traction under each wheel will result in a rear end that wants to slide to the side. I'd only use it (cautiously) if you are actually stuck, and then only enough to get unstuck.
I dislike the E-locker on the road so much that this time I opted for the limited slip diff. Much better.

 

The locker may help, but it only locks under 20 mph.

 

Nope. Use 4wd first, locker 2nd, if needed. Usually the rear locker, in 2wd, only makes things worse. Unless it's a steep, grippy, bumpy, gravel hill that you're spinning a tire on. Then it's fine.

In 4wd, it turns the Super Duty into a serious beast off road, or in deep snow.

 

Good info Guys,,thanx for the quick replys

 

Yeah it disengages above 20mph so it won't turn you sideways before you can blink when driving on slick roads be it ice or rain. A good limited slip will do the same thing also. My 17 will get sideways on snow and ice with elocker off and traction control and everything still on before it starts braking the wheels. These trucks with elocker are actually best of both worlds. With it off the truck will brake the wheel that's slipping to gain traction to let the one with traction grab kinda like a limited slip. Engage the locker and you are golden for most any precarious situation. 390 bucks is well worth it even if you never turn it on. At least it's there if ya need it.

 

In the winter I use it in between snow falls. When the roads dry up but the parking lots and side streets can still be a little slick, I use it. For the rest of time it is in four wheel, still not really that great on any type of an incline.

 

I live on a pretty big hill,,,sounds like ill have too screw around a little bit myself

 

I think so, that said I am in BC where we have many hills, mountain passes and a lot of fairly extreme weather. I have driven rear wheel drive cars and trucks in BC and Alberta over the years and its not that you can't, with a bit of planning and caution, but given the option I much prefer 4 wheel, all wheel or front wheel over a rear wheel drive pick up truck E-loc or no E-Loc at least where we live. That said it sounds like you have been doing OK up to now so it may work just fine in your part of the world.
