How do you find the axle gear ratio on a 2004 chevy 2500 express van?

Answer 1

There are four ways to find a ratio:

1 A dealer can normally tell from the vin number.

2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement info.

3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.

4 You can count the number of teeth on the ring gear and divide by number of teeth on the pinion.
