- The code to identify your axle gear is located on the front face of the right hand axle tube about three inches from the differential cover. The axle code is the first three digits of this code. (i.e. 8PS 0 103 2 = 3.73:1 Posi rear axle).
- Axle Ratio is based on drive shaft rotations to rear wheel or axle rotations. (i.e. if the axle ratio of your differential is 2.73:1, this would mean that your driveshaft turns 2.73 times to every one complete turn of the rear wheel or axle).
- Limited Slip is another term used to identify positive traction rear axles.
