Default VIN to find differential ratio

Can I user the VIN to find the differential ratio? We want to buy a travel trailer and the towing capacity is dependent on which rear end we have. As it is a used vehicle with no history, how can I find out?

Welcome to the forum..
I don't know if the VIN will provide it as easily as the RPO codes will...
you can find the RPO's in the glove box...
What year model are you looking for/at?

Default front and rear axle ratios

in regard to my 99 suburban K1500 w/AT I have a question: is the rear axle ratio the same as the front axle ratio? I don't know why it would not be, but just checkin'....
Thanks.

Default Gear ratio

I have a 2000 Chevy Blazer 4.3L 44 and I need to find out my rear end gear ratio so I can replace the rear axle bearings. I do not have a RPO code in my glove box that I can find. How else can I find out what it is?

This site will decode the VIN:

I don't know if the axle code is something that will be included or not, though.
