look for an id tag on the axle. if it doesn't have one take the cover off the differential and count the teath on the ring and pinion gears(big circle and small gear biting into it) then use simple division ex. 16 on the pinion and 44 on the ring equals 4.11
NEW ANSWER; He's right about counting teeth on gears, But you need to divide
the # of teeth on pinion gear into the # of teeth on ring gear, and round off #
That will be your gear ratio for sure.
A ring gear of 40 and a pinion gear of 13 is a 3.08 (40/13=3.0769...)
You can waste your time taking the dif cover off or you can do it the old fashion way. The easy way to figure it out is to jack the vehicle up off the ground put the trany in neutral and rotate the tire one full revolution and while doing so count how many revolutions the drive shaft turns. For example if you have a 4.11 rear gear ratio the drive shaft will spin 4.11 times for every single tire rotation.
It is a good idea to mark the back side of the tire where it is closest to the ground with some masking tape. That way you can see when you have made one full revolution as well as putting a mark on the drive shaft and axle housing. Not only is this easier it is alot cheaper than buying new diff lube and a gasket for the axle housing.
