Your axle gear ratio determines how many times your driveshaft rotates for every full tire rotation. The gear ratio can often be determined from the vehicle’s VIN code or listed on the axle tag. Some manufacturers, may not include that information in the VIN. The ratio can also be found by dividing the number of teeth on the ring gear by the number of teeth on the pinion gear.
