If only there was a way to fully disable the traction control.I’ve heard the factory limited slips don’t last very long. Locker is always fun in a nice empty snowy parking lot...........without 4WD engaged......lol
You can have the traction control turned off permanently if you have something like an SCT handheld tuner. The traction control light will stay on. As long as you don't mind seeing the light, it is a great way to do it.If only there was a way to fully disable the traction control.
My pile of to-be-installed parts includes a Detroit TruTrac (helical gear limited slip) for the rear and an Ox selectable locker for the front. Eaton also makes a selectable e-locker for the front 8.8.Darwin, you started this thread in Sep 2018. I think you were asking whether anyone had installed a "locker" in a 3rd generation Expedition. Now to me, a "locker" implies ability to "lock" a differential. Limited slip differentials do not lock.
And yet, the thread wandered off into space, with discussions about limited slip differentials, aftermarket and original, and about which Expedition models originally had these. It became very rancorous along the way. And, it may have been informative to some, but it doesn't seem to have been informative to you. I hate it when that happens.
I'm a newbie here now, as you were in 2018. I'm hoping that maybe you acquired some useful info elsewhere, about your original question. If so, I'd love for you to share that.
The 2017 I just bought may or may not have a limited slip differential, I haven't figured that out yet. But either way, I want a real locker that's selectable. I may settle for an ARB as a last resort, but have heard the air seals don't last very long if you're using the vehicle mostly on roads & highways, i.e. not mostly for offroading (typically far less mileage). Eaton does not make an E-Locker (selectable) for this Expedition, only their autolocker (not selectable), and I've heard bad things about the latter's behavior in onroad use. So has anyone found a selectable locker for this Expedition, other than an ARB?
