So with control track, the hubs must be normal hubs and neither manual nor auto locking.. right?
Correct. Think of the 'hubs' as not being locking hubs, but they typy of hub you would find on a front wheel drive car.
Which vehicles do have ESOF then? I innocently assumed the buttons = ESOF, shift stick = not ESOF. The owners manual metions control track and a brief note about Electronic shift control. But nothing I have clarifies exactly whats in the car SIGH!
In the states, the Ranger pickup, full size trucks, super duty pickups, and *some* Explorers (first-generation, from 1991 to 1994)Expeditions/Navigators. Across the pond? No clue.
Anyhow ... looking up control trac I found (
this).
Don't believe everything you read on the internet. The errors in that article are too numerous to dissect in a single post here. The majority of the Ford information is incorrect, misleading, or both. The person who wrote that article was right on some stuff, but significantly wrong on most of the Ford-related stuff.
The above link suggests the 4Hi and 4Lo lockout the electromagnetic clutch even in control trac equipped vehicles to ensure 50/50 torque front and rear. This would seem to agree with the other link on fixya. So I still think I have a problem.
It does, and it doesn't. Id does when you're driving down the road, but it's not like sliding a lockup collar in a conventional transfer case. Think of it as a pair of pliers gripping a part. You can vary how tightly you grip the part, or stop gripping it all together. That's how the system works. It does not act like a center differential. it acts like an on-demand, instantly-applied transfer case. It can split the torque from a f/r 0/100 split up to a 50/50 split, but cannot split it to a 100/0 split EVER.
In Auto, I could not make the front wheels spin. I presume I would need a longer runway to give the system time to detect the rear axle slipage, and for the slip to continue long enough to warrant it clutching in the front axle?
In auto, on the same loose surface, hang your head out the window and watch the rear tire. Brake-torque the truck until the rear wheels break loose, and they'll rotate about 1/8-1/4 of a turn and the t-case will lock for a split second, then unlock again almost before you can blink. Trust me, it's working. The fact that 4high works all but guarantees it. Have a little faith in the electronics.
