Put a mark on the tire and rotate it one turn, while watching the driveline count how many times the drive line turns and that will tell you! 3 1/2 turns would be 3:55, 2 3/4 would be 2:73, 4 would be 4:10, and so on!

Or if your rear end is stock and you want to do it the easy way, just open up the driver's side door and look on the sticker. You should see an axle code there. It will say "AX" with a letter beside / under it. The axle code will tell you what the stock rear ratio is:

Next to / Under "AX" you will see one of the following characters... 8, E, M, Z. Here's what they mean:

8=2.73 conventional differential (not for the 5.0s unless someone swapped a 5.0 into the chassis)
E=3.27 Traction Lok limited slip differential
M=2.73 Traction Lok limited slip differential
Z=3.08 Traction Lok limited slip differential

If you're stock, I'd just check the sticker instead of having to wait or instead of having to lift the rear end.

what the hell is wrong with mine then, I rotated the wheel once and the driveshaft only turndes 2 times exactly.

just check the sticker it's stock, my 4.10's turn 2500 rpms at the same speed, and a jump from 2.73 to 4.10 is an increase of about 1000 rpms.

but you go the long road just to see, but they are 2.73
