Mark a spot on the tire with a refence point on the floor. Turn the pinion and/or driveshaft (truck in neutral) and count the revolutions it takes to turn the tire 360 degrees. 4 turns is probably 4.10:1, 3.75 turns is likely to be 3.73:1, 3.5 turns is likely 3.42:1, etc.

- or - if the axle is just sitting there you can pull the rear cover and count teeth.

# of teeth on the ring gear divided by # of teeth on the pinion is your gear ratio.

41 /10 = 4.10
41/ 11 = 3.73

etc.
