Pull the cover,count the teeth on the big gear.Then count the teeth on the little gear,Divide small number into big number.Then you tell us what gear ratio you have :p :wink:

Get under the car and see how many turns of the driveshaft it takes to turn the side shafts one full turn. It should be ~3 3/4s turns for a 3.73.
