With a helper you can mark the tire and drive shaft and roll the car one
revolution of the tire and count the number of turn the drive shaft goes
aroung with two wheels up and positraction with both wheels turning the
SAME direction when rotated the same applies. With an open differential
one wheel on the ground 2 revs of the tire and count as best as possible
the number of revs of the drive shaft that is the ratio 3.5 times around
drive shaft is 3.5:1 Ed ke6bnl
