Rear Axle Guide

Every week we get questions about what rear axle I can put under my bronco. So I complained we should have an outline so people will read that first. But they wont. Oh well. Here it is off the top of my head. Please add/edit at will. I know I forgot all the dates and crap.

All axles are 1 ton, 8 lug, full floating axles unless specified. Obviously some cons wont affect your swap, like if you do not need VSS, or if you dont care you have a GM rear axle. Some are also a little bit biased towards what I like, but hey, if you didnt want to read and learn all the shit I did, then stfu. I also didnt bother with shaft sizes or bearing this and splines that. Because a 1 ton is basically a 1 ton, some have some weak spots. Your driving style, terrain, suspension and tires will affect breakage more than the difference between a 14b and a D70.

Please keep out the editorial bullshit. If you post, post some good info or links.
