Bob, if you have the new vehicle window sticker, the axle ratio would be listed there. If not, there should be an axle code on your drivers side door sticker. Mine reads B6, and that would be a 3.73 limited slip. Here are the codes I found for the 2006 and 2007 F150s:
Axle Codes:
L - Limited Slip Differential
C - Conventional Differential
Code ****Ratio
19 ***** 3.55C
25 ***** 4.10C
26 ***** 3.73C
27 ***** 3.31C
B5 ***** 4.10L
B6 ***** 3.73L
H9 ***** 3.55L
You might have to do a little searching to see if these are the same codes used on the Expedition, but since the Expedition is built on a F150 frame, I suspect they might be.
