If you have the driveshaft disconnected, you can just jack up the rear axle and measure the number of revolutions of the wheel per full revolution of the rear axle yoke. 3 3/4 = 3.73, 3 1/2 = 3.5, 3 1/4 = 3.25, and so on.

There's also info on the driver's door warranty tag pertaining to rear axle ratio. Should be the last set of numbers on the second line (after AXLE). You can decode it here: http://home.earthlink.net/~threynolds2/ ... s6166.html

If the differential is sitting on the floor, draw a mark on the ring gear, and a mark on the yoke. Rotate the yoke and count how many turns it takes for the ring gear to turn once.
