I think that, right there, is the problem. You guys take things way too seriously, and (maybe wrongfully) assume that I am trying to be taken seriously as well? Why can't building axles just be about fun? I thought that the entire first post of this whole thread kind of set the tone that I am not trying to be taken seriously.
I seriously do appreciate all of the information and tips from you guys, but I also think you guys take things way too seriously. Lighten up and let's have some fun playing with axles. Who gives a flying fuck how much its going to cost? Who gives a flying fuck if it all gets built and I find out that I hate e lockers or that selectable hubs are garbage. I am at a place in my life right now where I have worked my ass off to get where I am. I donated over $17,000 to offroad communities across the country last year. We will be above $20k this year. If I have some expendable tax-write-off-cash to blow on having fun building some stupid axles, then why not just let me do it?
We also, I think, have different definitions of what "off the shelf" means. Obviously, I am building axles that I wont be able to get parts at auto parts stores. My goal is to pick parts that I can get within 2-3 months, from companies that aren't going anywhere, that (typically) have inventory available on their shelves, using parts that are commonly used parts for the offroad industry and also won't be going anywhere for a while.
I am fairly certain that 8x6.5 05+ SD UBs arent going anywhere for a while. Same with Tundra third members and 5.29 gearsets. Same with wilwood calipers and rotors. As for shafts, there are tons of companies around that will make custom shafts. If one goes under, I will call the next one. My only real concern when it comes to parts availability is the Tundra elocker from Eaton. It is hard to say whether they will keep producing it since it doesn't have a ton of aftermarket demand. But I am also sick of using ARBs, so that is a risk I am wiling to take for now.
THis might also be the point that is causing so much uproar... I am trying to build a "rock bouncer" axle by using as many commonly used parts as possible, but without doing what everyone else has done before because that is just boring. Can there be a different recipe that can work? Maybe there is, maybe there isn't. But this is my build and what I am going to do. How about we all have some fun with it rather than whatever this whole thing devolved to over the past 3 days.
