it should have the ratio stamped on the crownwheel and pinion. make sure they were a matching set out of the same diff. Cheers.

Count the teeth on both crown and pinion and divide the pinion amount into the crown and you will soon know I think?

does the diff ratio relate to the amount of revolutions the pinon completes in relation to the amount of revolutions the crown wheel completes? e.g: In a 3.45:1 ratio, Pinion has to complete 3.45 revolutions to turn the crown wheel 1 full revolution?
