    I have always heard of how you mark the tire and driveshaft, then see how many turns of the driveshaft it takes to turn the tire once. I tried this for I think the third time and it hasnt worked out to well. This time I spun the driveshaft and my 14 Bolt axle turned the tire once after only 2 turns of the driveshaft. I know my axle is not 2:1 gears. So what gives?? And I did the test where you turn one wheel forward and the other wheel went backwards so a locker or two is definately on the list. :cool1:

    if you only had one tire off the ground then the differential gears are going cut your ring and pinion ratio in half; So if it took two turns of the pinion yoke to make one revolution of the tire you probably have 4.10 gears, which is a common axle ratio for a 14 bolt.

    OK ya that sounds better. When I tried it with both tires off the ground one wheel would turn about halfway around then the other wheel would spin. Thanks :grin:
