i have a 2018 xlt with 4x4 single speed tc and the 8.8 rear end without locker. auburn and eaton offer e-locker for the 8.8 with 31 spline shafts that should mechanically fit.

does anyone know if that works with the 4x4 drivemodes? as far as i figured out the locker shouldn't make that much differences in the drivemode selection since they can be selected with or without locker.
unfortunetely i don't have the oem but think about adding the auburn or eaton version.

any experience out there?

cheers, Lars

thanks for the input but that was not my question.

the expedition is there and i don‘t have a locker. the original stuff is a 9.75“ carrier with different gears so i would need to change front and rear. not really cheaper and an option.

the question is if you (or anyone) knowy if that messes up the drivemodes since they don‘t expect a locker. i would say no since the system just doesn‘t see the loss of traction and would act „normal“.

I can't think of a reason it would matter. You would only be using the locker offroad anyway. I would go for it if you think you need it.

The traction control acts as a locker if you Leave it on. Its free as you already have it.....

This ^, in any of the various 4WD modes on the late 2nd gens and 3rd gens there is traction control at all 4 wheels and they use braking bias to force the wheel with traction to spin. In 2006 Ford removed the limited slip option altogether and replaced it with the AdvanceTrac with off road mode. They brought the LSD back at some point but that likely negates the TC in rear while operating.

But the braking software based virtual limited slip differential is just that, a limited slip. Which means the traction control system will let a wheel slip. My driveway is sloped and has a transition from gravel to concrete. At the transition, traction is better on one side than the other. I use the locker to park the trailer otherwise the LSD will continue to slip on the one side and dig a bigger and bigger hole in my driveway. And I use it when I park on wet grass in the side yard. Again, I don't want any wheel slip because I don't want to dig holes in the lawn.

Did you buy a 2wheel drive model?
