If you are trying to see if the rear end is the same gearing as your front end you will need to take the covers off both. Either count the ring gear, and pinion gear teeth, or get the last numbers off the ring gear which are the ring and pinion tooth count.

or you can jack it up and count how many driveshaft rotations it takes to make the tire rotate once. 4 1/2 times equals 4:56, 3 3/4 times equals 3:78 and so on
