    <font color="green"> Gears generally have the tooth counts for the ring and pinion stamped on the edge of the ring gear. If when you divide the larger number into the smaller one, you get 3.73, then it's 3.73. </font color>

    The best way is to pop the cover and count the teeth or look for the stamping on the ring gear. The other way is to jack up the back of the truck and put some marks on your tires and driveshaft and spin them several revolutions, counting driveshaft and wheel turns. Then divide driveshaft revs/wheel revs and look for the closest standard ratio (because your counting process wasn't perfect).
