• 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. 8HF 0 103 2

  = 3.08:1 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.
