Gear Ratio
Can anyone tell me a somewhat accurate way to determine the gear ratio without pullining the Diff. cover off. I Heard jack it up and wheel to driveshaft turning can give you the ratio. But I dont Know the formula. Thanks 1979 Ford Bronco with 38.5

even easier way is like torque said, but turn the wheel 20 times, then take the # of drive shaft rev's devided by 10 = ratio
rev's/10 = ratio
rev's/10 = ratio

You could look at the tag on the diff housing, you should have a ford 9''. If you don't and you have the vin code and rear end code you can go to Mil1lion's website he has a link to a decoder.
