Determining Axel Ratio?!

[Abn Panzer]

Can anyone tell me how I can determine what the Axel Ratio of my Tahoe is?
It is either 3.42 or 3.73 (According to the Manual)

2004 Tahoe
2WD
LT
5.3

Was wondering as it is the difference in 1000lbs towing.

Tried searching the forum but cant find an answer.
Thanks!

Look for one of these codes in your glove box. GU6 for a 3:42 and GT4 is for a 3:73 a G80 code means you have a locking diff..
