Ok.I think I have come up with 2:73's but how do I know for sure since someone could have changed them?(I only tryed decoding the rear axle code)All you do to look is just take off the rear end cover right?What would I have to do to find out what they are?How do the different ones look I mean.I thought if you had lower gears like 4:11's compared to 2:73's you would have alot more spin in your tires.Is this right.If so mine probally arent the 2:73's since they can spin the tires pretty good.(Even though the back ones are only 14 by 8's I think)Thanks!

take the diff coveroff that is the ONLY way to know "for sure"
look at the ring gear stamped on it will be a ratio or 2 numbers representing the # of pinion teeth and ring. for instance if its a GM " Im making this up" but for example
GM 2837643827364 41-11

So the last two number sequences tell?What would be What?

In that example, 41-11 is the number of teeth on the ring and the pinion, so 41 divided by 11 equals 3.73

Once you find your numbers, you can simply divide them, or you can count the teeth on the ring gear and the teeth on the pinion gear.

What is the code stamped on your axle tube? You can decode that, and then jack up the car and count the rotations of the wheel for each single rotation of the driveshaft. If they come up close, then you have a good estimate.

But counting teeth is the only "true way"
