VIN information
 

Is there a place to look up the vin on your truck to see information on rear end specs or anything like that? Just curious if I could look up my vin and make sure it has 3.73s and all that.

Try this:

thanks i will give a try!

thats what I was looking for, thanks again!

Or you could lift the back of the truck and count driveshaft revolutions and tire revolutions. Put a piece of tape on each for reference. If the wheels spin in opposite directions then hold one still while you turn the other. Block the front tires before lifting the back or something might get squished when the truck rolls down the hill. ;)

The tag on the axle as well.

Now that's just too easy. :-X04
