GEN 2 Locking the rear Diff in 2wd

[NASSTY]

The 2011 F150 4x4s were the same, you could only lock the rear in 4x4. So people were swapping in 2011 Raptor TCCMs and 4x4 switches so the rear would lock in 2wd. Then in 2012 Ford changed it so you could lock the rear in 2wd on F150 4x4s. https://www.f150forum.com/f38/electric-locking-rear-diff-318615/

And why did they stop? Sounds like breakage problems.

Gen 2 does this no problem.

-Switch to baja mode
-switch back to 2wd
-switch tranny to manual
-hold traction button for 5 seconds

Enjoy all the tail slides, donuts, anti-lag shifts, you want.

I'd read something like this somewhere. Have you confirmed it to be true?

I don't believe this locks the rear end. But I do a lot of ******* around high speed off road and that is my go-to mode for hooning. As noted in the video, I have never had issues with both rears spinning.

Doesn’t the truck lock the rear as needed to keep traction? Even in Normal mode while it’s not full time, won’t the nanny’s activate it as needed real-time? Curious on its behavior. Off road is the only place to use it locked by any means other than a straight line street race.

I believe it only locks both under loss of traction at both wheels, but you want it locked in 100% of the time, including around corners etc especially in the soft stuff, when climbing hills, you don't want the rear end going from one tire to the next in the rear. Doing the bunny hop thing, lol

I dont think it locks the diff, I think it plays around with braking to limit wheel spin.

I'm anxious to play with my truck in the snow. The 4-Auto setting in my Chevy is perfect in the snow. There's just enough delay in the system that you can kick out the rear and get a slide started before it goes into 4 wheel, then you can finish your drift in 4 wheel. I'm hoping my Raptor is similar.

Agree for sure. So 4A any more locking action or has to be 4L/4H to be full time locked?

I have much more experience with plain posi(clutch/cone) and spools then with electronic locking rears.

Argh, That’s not performance or fun behavior. Just more safety and reduction in performance. Makes sense how they would implement it this way however.
