There are four ways to find a ratio.
1 A dealer can normally tell from the vin number.
2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement
info.
3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.
4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.

∙ 14y agoIf the front is 3.55, then the rear needs to be 3.55
The most likely ratio is 3.55-1.
i believe it would be 3.11
3.55 or 4.10 : 1
Could be 3.55, or 4.10:1
They used a few of them. Open the cover, count the teeth on the big gear ( the ring gear ) next count the teeth on the small gear ( the pinion gear). Divide the big gear by the little gear and that is your ratio.
it will be the same as the rear diff
