I know it's probably been gone over a thousand times but, How do you tell what front gear ratio you have. Theres a tag on my front axle that says 3.73. Is that what they are? I searched til' one of my eyes fell out and all I got was confused.

If you didn't have the same ratios front and rear, there would be some horrific "binding" anytime you were in 4WD, especially on dry pavement (which isn't a good place for 4WD at any time).
AAAH, in my searching I got confused I was reading a bunch of posts that said you could be x amount different front to rear, Hence my confusion.
LESSON: Don't believe everything you read on the internet, especially when it defies logic.
It depends on the situation. If you were building a dedicated mud racing vehicle you would set the front end up where it spun faster than the rear, but for any street driven vehicle they must be the same.
They do not always have to be identical. Back in the days before 4-wheeling was a mainstream sport for the masses you could not get every ratio for every differential....it was not uncommon to use somethng like a 4.11 in the rear and a 4.09 in the front.
A slight variation in gearing like 4.10's to 4.11's will be OK in the dirt, but like I said before, no four-wheeling on dry pavement if you don't want things to start binding! Even with the VERY same ratios, small differences in tire wear will start to be significant, and it's hard on the entire driveline.
