Place wheel chocks under the front tires, place the trans in neutral and jack up 1 rear wheel off the ground so you can spin the tire. Have a buddy slip under and make a chalk mark on the driveshaft. Leave him under there to count revolutions of the shaft. Turn the tire exactly 10 revolutions while he counts revolutions of the shaft. Now, divide the shaft revolutions by the tire revolutions. 35 1/2 revs on the shaft (35.5/10) = 3.55:1, 38 1/4 revs on the shaft (38.25/10) = 3.83:1, etc., etc. I have no idea what the actual ratio might be. I'm just using these numbers for example.
ya ! ....... thats what I said .......
