Need help with axle codes

[Flatbedford]

I went to look at a 2004 F250 PSD 4x4 automatic crew cab short bed today. The truck looks and drives very good. Is there a place on this site or on another that a can decode the VIN, axle, trans, etc.? What ratio would axle code c1 be? Any thing in particular I should check about this truck? I'm new to the Superduty trucks.
Thanks,
Steve

Non dually it is a 3.73

Dually could be 3.73 or 4.11.

Axle code on my 2004 is D1. I have a Limited Slip 3.73

Apparently C1 is also a Limited slip 3.73. Check the site below

Is 2004 a good year for these trucks? I have a '96 and a '70, both gas powered.

Have your dealer run an Oasis report on it. It will show all of the warranty items, plus any recalls that were done/taken care of on the truck. If it is a private party, just copy down the VIN.

My 04 has been good so far and I have 62,000 miles on it now. I have had the VGT sensor replaced once, EBP sensor twice, EGR has been replaced twice (a cleaning can also take care of it), the EGR cooler leaked and was replaced. Befor camping season this year I had head studs installed as I had stretched the head bolts (quite common in trucks with ANY type of Chip/tuner. Also happens on stock trucks, just not as often).

I tow a 13,000+lbs 5th wheel RV with mine and I have been quite happy with it. Towing I see typically 9 to 9.7MPG. Unloaded all highway at 70MPH will net me 19.8 or so. Typical commute which is 60% highway and 40% city I see around 16MPG.

Now that I bought my Mercedes 300D the Ford has been relegated to when I tow or NEED a truck to haul stuff.
