a little help with her rear end

[Luvlegs]

Quote - DennyB from the FAQ section:

Another way is to do this is....
With an open rear (non posi)- jack up one rear wheel (please use jack stands), put the truck in netural, turn the rear wheel and count how many times the drive shaft turns.
Multiply the turns of the drive shaft x2 and divide for the ratio. This is most accurate if you turn the wheel about 10 times.
With a posi rear, jack up both rear wheels and turn the same way as above. use the actual drive shaft revolutions with a posi.


OK, so I turned the wheel from 12 o'clock position all the way around twice (2xs) and then stopped at the 1 o'clock position - the drive shaft turned twice - exactly. I can't seem to figure out what I have here..... 2(2)/ 2.17 = 1.84?? Thanks for the help!
