Expedition export modell with lockers?

Hello,

I think about buying an Expedition from 2003, about 100k mileage.
5.4 liters, 224 kW, Eddie Bauer Edition. (canada edition)

The seller keeps writing and telling me that for sure he/it has lockers at the front ant rear axle.
He's a private person and from his grammar he does not to be thaaaaat clever :-)
Unfortunately I'm also not a mechanic and not a Ford specialist, either.


All information I found gave the information that it was possible to order the EB Modells with Limited Slip Differentials, but I think they would not be 100% lockers, would they?
That guy tells that his EB has 2wd and 4wd mode PLUS two reduction modes , could someone please confirm his information? Or tell me, what to tell him to figure that out? (I think about something like a modell code or something similar)

He lives about 4 hrs driving away so I'd like to know as much as possible before sitting 8 hrs in my car just to figure out that he was wrong.


Thank you in advance

The "Traction Lock" unit is the only one Ford has offered as OEM. The dealers will often sell and install any type of locker the customer wants, usually after he takes delivery of the truck. A locking front differential has not been offered in my recent memory.

The selector is 2WD, A4WD, 4H and 4L. A4WD is a sensing mode that kicks to 4H when wheel slip is detected and stays engaged until the slip is gone.

Is the "traction lock " a real lock then?
Additionally wikipedia.EN is giving some information about a "Four-wheel electronic traction control was now available as an option, and simulated front and rear differential locks"
What is that and what is that doing? The same like mercedes? Braking the spinning wheel? Ford Expedition 2nd Gen Wiki


Anyways, thanks for the explanations to the selector. that was also helpful

Traction Control is not the same as a "Traction Lock". The traction Lock differential is Ford's name for a locking or limited slip differential that is very similar to GM's Positraction in that they both use clutch packs to lock the axles into the same speed when power is applied. The earlier true locking type of differential is a mechanical type of operating system that uses a cam and ramp design sold as "Detroit Locker" products. They are very effective but pretty noisey for a non race type of vehicle. There are also Air Lockers, Electric Lockers and probably many that I have never heard of. Just be careful of a welded spider gear locker A/K/A a "Lincoln Locker" as that will cost a ton to reverse and can cause problems for the inexperienced driver in any adverse conditions.

I don't have any experience with the "Traction Control" systems so I'll not comment on it, there are several on the forum that can make informed statements on it.
