When turning the driveshaft or the wheels to see what gears you have , like what is the ratio, like 4 complete turns equals 4.10's ( just an example )... i think i have 3.73s in my car, i wanna check?

Turn the rear wheels once, make sure both rear wheels go around 1 full circle. Count the # of times your driveshaft turns. That's your gear ration. So if the drive shaft turns slightly more than 4 times then you probably have 4.10 gears
