REAR AXLE
Determining Axle Ratio
The drive axle is said to have a certain axle ratio. This number (usually a whole number and a decimal
fraction) is actually a comparison of the number of gear teeth on the ring gear and the pinion gear. For
example, a 4.11 rear means that theoretically, there are 4.11 teeth on the ring gear and one tooth on the pinion
gear or, put another way, the driveshaft must turn 4.11 times to turn the wheels once. Actually, on a 4.11 rear,
there might be 37 teeth on the ring gear...
