With a helper you can mark the tire and drive shaft and roll the car 
onerevolution of the tire and count the number of turn the drive shaft 
goesaroung with two wheels up and positraction with both wheels turning theSAME 
direction when rotated the same applies.  With an open differentialone wheel on 
the ground 2 revs of the tire and count as best as possiblethe number of revs 
of the drive shaft that is the ratio 3.5 times arounddrive shaft is 3.5:1  Ed
