locking differntial (posi)
I've been considering a new truck but I understand that the new fords cannot be ordered with a manual locking rear differential. Does anyone know if a limited slip or posi rear unit from an earlier year Ford can be installed in a 2016 or would I have to go for an aftermarket one like an eaton trutrac? I do NOT want the Ford electronic locking differential.

I don't know how you get away from the stock E-locking set up. Add the Eaton. Earlier stock Ford stuff is limited slip, not locker.
E locker using the brakes works fine up to a point, and that point would be overheating or wearing out the brakes I suppose.
Hey, it's just an electronic version of the two brake pedals our Ford NAA and Allis Chalmers (and every other old farm tractor) had.

Ford does use the brakes as part of its traction control strategy. they call it "one wheel spin control"
but the factor e-locker is a true locker, not just brake enhanced traction control.
the only real downsides to the factory e-locker is that it requires the driver to engage it, and it will automatically disengage at 35mph unless you are in 4-low, where it will stay engaged until 60mph (unless they changed the strategy for 2015/16).
other than not having full time limited slip, the e-locker appears to be very reliable.
I have not studied the 15/16 enough to know what changes have been made to the rear axle so I'm not going to comment on backwards compatibility other than to say if history is your guide, it is likely that not much has changed.
IIRC, the 3.5N/A and 2.7 Ecoboost both use the 8.8" while the 5.0. 3.5 Ecoboost both use the 9.75". However, the 2.7 Ecoboost gets the 9.75" with the "2.7 Ecoboost payload package"
good luck!

Like mentioned, the older traction aids are limited slip which were marginal at best. With brake based traction control you are pretty much getting almost the same thing just not as aggressive and a lot of limited power because of the traction control itself. The elocker is an actual locker with a 50/50 split on power of course with the truck being a nanny above certain speeds but the better than the 70/30 (at best) split in a good factory limited slip. If you really want a limited slip you can go aftermarket or and older factory until will fit. Not 100% on which bearings are required depending if it's a 10.25 it 10.5 unit but it can be done.
