Anyone out there have any good bookmarked pages involving different axles and their tech specs?

I think I'm confused on which axles are 3/4 ton and 1 ton. I need to do some learnin.:popcorn:
 
a 250 or 2500 is a 3/4 ton truck, a 3500 is a one ton truck. That's where the names come from. A d44 or 10 bolt can be either 5 lug 1/2 ton or a thicker/stronger 8 bolt 3/4 ton. A 60 can be 3/4 or one ton. d 70, 80 and higher are 1 ton+. 14 bolt can be a 3/4 or 1 ton axle. 10.25 sterling can be either. 10.5 sterling/visteon is a 1 ton axle. There are more and there are exceptions to all of those. Lots of different versions of the same axle.
Any of the jeep non-truck axles are 1/4 ton.
 
Let me see if I understand correctly:
So the tonnage is more or less based on the vehicle it came in. Some axles can be either because they were offered in two different sized trucks and had different hubs, etc.

Next question:
Why is an F250 considered a 3/4T truck? Seems like it would be more of a 1 1/2T truck if this is based on payload capacity. (What is the tonnage rating based on?)
 
a good rule of thumb for frount axles if it came out of anything other than a 350 or 3500 it's not a 1 ton axle.for the rear pretty much if it came out of 250,2500,350,3500 it will be a 1 ton axle. the rear 1 ton and 3/4 ton are as a rule the same unless the 350,3500 is a dually then will be a higher rated axle.i know this is not 100 percent but it get's me by.
and the tonage is rated based on how much weight they can haul,witch is a little bit diffrent on each model but to be considered a 3/4 ton it has to be able to carry a certain amount of weight and so on. hope this helps.
 
GMd44 or 10b will be 6bolt or 8 bolt.
No 5 lug 4x4 GMs
