Best way to figure out what your diff ratio is…
Tie a length of string on the drive shaft U-Joint
Roll the vehicle one tire rev using the valve stem as the datum
Count the number of full turns of string and that will the whole number of the diff ratio
Check the fraction of turn left on that string and that will be the fractional number of the diff ratio.
Remove the string
3 full turns is a 3.xx
3/4 of a turn is a 3.73
And so on…
