You can get a pretty good idea by jacking up the rear axle of the car. Put it in neutral. Turn the drive shaft and see how many times you have to turn it to make one tire revolution. If you turn the drive shaft 3 1/4 turns then you have a 3.23 ratio. You could also pull the diff cover and look at the number on the ring gear too.
