Look in your glove box, It should have a sticker with paint code, engine, GEAR RATIO, type of rear end, and some other stuff i think.

If not there should be a small tag on one of the bolts on the rear.

Mark the tire and the driveshaft,drive ahead one turn of the tire,count revolutions of shaft. Should be easy enough.

Sticker in glove box is gone, door jamb sticker does not have gear ratio, nothing underhood, no tag on rear. Non stock tire size.

Maybe by vin?

Awesome good info BigGreen.

I second the wheel spinning. Jack the truck up, put the rear axle on jack stands, spin the passenger side tire and count how many times the driveshaft spins. Obviously mark a spot to be sure.

No, mine has the 5.9 gas. A V10 would be cool.

Well since they don't make em and only made them from 94-03 they aill become collectable I hope and desirable. Anyway I love mine and wouldn't trade it for a 2012 Cummins (well maybe even up).

And I 3rd it for the simple reason is a previous owner may have done a gear swap rendering the glove box/door jam sticker info incorrect.

Thanks guys. I guess I will have to count the revolutions at some point. This truck has been slightly modified with a leveling kit and did have larger tires on it before according to what the previous owner told me about the previous owner.

I'm going to deal with the leaking valve cover gaskets first.
