By Using Manual Technique

This method of searching for gear ratio requires disassembling the rear axle and driveshaft. It is better to seek a professional’s help in such scenarios. 

Most of the time, you can find the gear ratio stamped on the driveshaft covering or on the surface of the ring gear. 

If you don’t find it stamped, check for the last four digits on the ring gear. These numbers show the teeth count of the ring gear and pinion gear.

The ring gear has a higher value of a number, whereas the pinion gear has a lower value. Divide the ring gear teeth number against the pinion gear teeth number to know the gear ratio of the axle.

You can also manually count the teeth of the ring gear and pinion gear and then divide them to know the ratio of the gears.

Therefore, knowing how to find the axle ratio of the Dodge Ram 1500 gives you a lot of hidden but essential information.
