Just to the right of where the AXLE should be mine says E with TR just above that. If that is what you have then you most likely have 3.73 open diffs as well...
I think that what Ford did with these truck is only listed the axle code if you got something special. If you have nothing there then it is 3.73 open by default.
If your axle code really did start with E that would imply a D70 with LS. I thought a D70 was a front axle. At any rate your axle code doesn't include an E, the axle codes for the Excursion would all be for the Sterling 10.5 so possible values would be
31 — 3.73 non-limited slip, F-250/Excursion
C1 — 3.73 limited slip, F-250/Excursion
C2 — 4.10 limited slip, F-250/Excursion
C3 — 4.30 limited slip, F-250/Excursion

Call a Ford dealer with your VIN, if they are nice they will tell you what you have. My local dealer told me over the phone. If you call and they won't tell you just call somewhere else.

According to Scott an unlisted code DOES NOT imply that you have 3.73, he has no code and he has 4.30

Tell them that you just moved to Vermont and you are thinking of getting service from them, and oh, by the way can you tell me what axles I have, here is my VIN.

Nice... I wish I had that. Although I am am looking at going to 5.13 gears and 38" tires which will give me a final ratio of 4.30 anyway. My point is even if I had the 4.30 gears now I'd still want to regear.
