LSD, When you rotate a wheel or axle, the other side will turn in the same direction. An open diff will turn opposite.
Ratio. First inspect for a data tag, if there is one, it will most likely be stamped. Else you need to open the case and do some math. Count the teeth on the Crownwheel and pinion, then divide the crown by the pinion. I.e 37 on the crown and 10 on the pinion, is 37/10 or 3.7:1
