If you're referring to rear end gear ratio, it's simple.
Just look at the white door tag under "Axle" there is a code there.
These are the most common ones.
17 = 3.31 non-limited slip
19 = 3.55 non-limited slip
H6 = 3.73 limited slip
H7 = 3.31 limited slip
H9 = 3.55 limited slip

FWIW to anyone:
The tag on the door of my 2005, shows "Axle 15".
A search of my VIN on VIN Decoder provided this info:
"Axle Ratio
1) - Rear 3.73, 3.73, 3.31 (3.31 min/3.73max)"
Not sure exactly how to decipher it; but assuming it has a 373 axle ratio. is my assumption correct?
