I’m confused…why would you need the e-lock in two wheel drive?
If you know your truck and sound of your transmission/tires you should have problems going faster in 4LO.
just asking because I don’t understand
Times I lock the rear (not off-roading):
1. I have the hard downshift problem (several warranty visits to the dealership - a couple of TCM re-flashes and it's better but still there). My truck hangs in 3rd until it is all but stopped. If I start to give it some gas before the truck is stopped, the truck jerks into 2nd or 1st (throttle lag combined with hard downshift) and jumps forward. On a wet/loose surface that's a guarantee that my traction control will activate. If I have the axle locked then there's no slippage.
2. San Diego does not see a whole lot of heavy precipitation. It doesn't take much to make the roads slick if the sky decides to grace us with some always-needed rain. Leaving a red light at an intersection I will get wheel spin with mild acceleration as I cross the white crosswalk paint lines. For those times I lock the rear at the red, accelerate across the intersection when the light turns green, then unlock the rear.
3. Getting up/down my truck ramps to change the oil. I have a gravel driveway so traction is at a premium. I lock the rear when going up and down the ramps (especially up) so that I don't dig a hole in the driveway with my right rear tire or slip on the ramps. I'm usually in 4LO also but having both rear wheels driving from the get go makes a big difference.
4. Because that's the only option for the ORG. I was on the fence about an e-locker (never had one before) but the ORG was a 'must-have' on my list so that made the decision for me.
There are other times that pop up that the e-locker comes in handy but those are the recurring times I use it that come to mind.
My last 2 trucks had LSDs and there are maybe a handful of times (out of the last 20 years) that I didn't foresee the need for extra traction and thought "I'm glad the LSD engaged". I'm not young so hot-rodding around and doing donuts in the shopping center parking lot on Saturday night are way in my past. I can foresee the need for traction 99% of the time so I can hit the button on my dash (e-locker or 4WD) to be ready for it. Maybe if I lived somewhere that had all 4 seasons I would be singing a different tune but down here winter is only about a week long and that's because it might...
might...get down to 40F at night during that time.
