Axle ratio from VIN?
I am contemplating buying another Sport-Trac. It is an '04, VIN 1FMDU77K34VAxxxxx. The one I have now has a 4.10 ratio and doesn't get the mileage that I would like. Can you get the axle ratio from the VIN I posted? I would rather not buy another one with the low gears.

Does it not have a Vehicle Certification Label on the door?
Axle codes are:
42 — 4.10 ratio, non-limited slip
46 — 3.73 ratio, non-limited slip
D2 — 4.10 ratio, limited slip
D4 — 3.73 ratio, limited slip
Did you try taller tires to raise the final drive ratio? I think 265/75R16's will fit without much of an issue. Higher gearing does not always mean better mileage either..........
I have 3.73's and wish I had the 4.10's.

It's about 3 hrs. from me and I haven't gone and looked at it yet. I'm not terribly worried about the mileage of the one I have now and have done nothing in an attempt to improve the it. My daughter just totaled her car and I was contemplating letting her have it and buy a newer one for my wife. I was hoping to get one with the OD transmission and higher axle ratio and hopefully higher MPG.
I double checked the VIN and noticed that I had it wrong. The correct one is 1FMDU77K34UA28844.
