Re: Rear End Ratio

Because your center section is open or non- posi, you will need to rotate the tire two complete rotations while counting the number and fractions of rotation of the driveshaft to find the approximate ratio . In an open diff, when you hold one wheel solid the action of the spider gears will cause the non-solid wheel to travel at an increased rate. This is not the case in a locked diff or a properly functioning posi. In a posi you rotate the tires one revolution while counting the driveshaft rotations. This will give the ratio directly. Bruce
