It is part of the heavy-duty trailer tow package.
I guess they dropped it then. I do have the Heavy duty Trailer package. It no longer shows limited slip anywhere as being available on 2023 except AWD and with an optional package. I think I do have 3.73, but even at that I am finding confusing information. I keep falling back on the 3L designation and still don’t have conclusive information on what that means for 2023
You are suppoerting exactly why I’m so perplexed and made this post. Look at that chart of yours and explain to me why mine is 3L and what that means.
According to Ford on a 2023 Expedition, if you have the heavy-duty tow package you have the 3.73 axle. If you have a 3.73 2E66, then it is an Electronic Limited Slip axle. The 2L is not. https://www.ford.com/cmslibs/conten...df/2023_Ford_Expedition_Towing_Info_Dec16.pdf
It clearly makes no sense. I crawled under it last night and don’t see any cables or actuators of any sort.
You don’t have the Elsd then
Do you still have the window sticker? It should show the tow package and what axle you have. Upon researching more, I read around 2021 and later, there were 2 axle options for the heavy-duty tow package. 3.73 "2E66" with Electronic Limited Slip and 3.73 "2L" without Electronic Limited Slip.
I do have the window sticker. It does not show what is included in the HD Tow package. As I have shown in posts above, nothing shows a 3L axle in any of Ford‘s literature, but I have it….whatever it is.
The window sticker will definitely list the rear end gear set in the 4x4 model and basic AWD model.
Mine is rear drive and the window sticker says nothing about the axle ratio.
According to the chart you attached 3L is the axle code for the Super Duty Limited Slip (F250). Not sure how it made it onto an expy but that's the code.
The code for the axle ratio is on the sticker on the driver's side door. The tow guide for each year can tell you which code is tied to each axle type. It has something like 10, 15, or 3L for the axle code.
The heavy tow pack Expedition gets the 3L 3.73 rear end. Its an 8 passenger rated for 9200lbs SUVs are built different than trucks due to passenger weights and crash safety stuff. When built for heavy tow they get heavier truck equipment vs light truck equipment.
I’m guessing you have not read many of the posts. All that has been covered. My code is 3L. NOTHING in the tow guide for the 2023 Expedition says 3L exists. Screenshots of all that information are posted in this thread.
