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.
Could be either 3.55 or 3.73 :1
3:48
3.07 or 3.73 to 1. Could be either.
Jeep Wrangler only,
The 4 cylinder models have a gear ratio of 4.10:1

Could be 3.07, 3.55, or 3.73
Could be either 3.07 to 1 or 3.73 to 1 Both were an option.
4.11's would be perfect.
My jeep wrangler keeps loking in gears
I have a 95 and the gear is 4.11. It is on a little placard on the axle diff. cover. Can be either on the front or rear. Good luck.
