Block the front tires, put the transmission in Neutral and jack up the rear.
For open Differentials, jack up one tire, spin wheel 2X, and count pinion/driveshaft rotations.
If locked or Limited Slip, jack up both tires, spin wheels 1X (both wheels will spin together) and count pinion/driveshaft rotations.
About 3 and one half rotations equals 3.55 gears.
