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.
If the front is 3.55, then the rear needs to be 3.55
The most likely ratio is 3.55-1.
3.55 or 4.10 : 1
i believe it would be 3.11
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
my truck is a 2 wheel drive ext cab with a 5.7{.350} engine. its a 1500 i have a new rear end from a v-6. i need to know if the gears are the same or are close enough to be used?
2.833 is the rear-end gear ratio
The rear end gear ratio on a 1980 Oldsmobile is 3.73, in the overdrive gear. The low gear ratio is 1.43.
a safe-t-track rear end has RPO code G80-which is a positraction rear end and a 3.23:1 gear ratio was available having the RPO code GU5
