If the tag is not present, you can get a rough estimate by putting a chalk line on the tire and on the drive shaft. With the vehicle jacked up spin the wheel and see how many times the drive shaft spins with a full tire rotation. If the shaft spins about 3 3/4 times you probably got the 3.73. If it spins a little over 4 times you probably got the 4.10. To get it exact you can remove the differential cover and count the teeth on the ring gear and pinion gear then divide the two to get the ratio.

Two easy ways to tell...
1) On the back of the rear differential there's a metal tag sticking out, with various numbers on it, like 8.8 for the 8.8" rear end, and probably a 3 73 or 4 10 for gear ratio. If there's a L between the numbers ( 3 L 73 ) then it is a limited slip. Or . . .
2) The sticker in your door jamb will have info on it. One section will have the Axle code, 97 or R6 or something. Go to http://www.therangerstation.com/tech_library/Axles.html for all the info you might need.
By the way, anyone here running 4.56 gears in their ranger?
