I'm not just kicking the tires here, I am actively building information for a rear axle upgrade on my 2dr jk. Let me tell you where I am and where I want to go....
2dr JK with LS swap, 40" maxxis treps, stock rear 44 with original 30 spline shafts, 5.13 gearing, and a locking diff. It has been good to me since it was new, no breaks or complaints. I am not oblivious to the fact that its going to give it up at some point the more and more I beat on it. My gut tells me that I will spin a tube on it at some point and roll up all the shit connected to it on one side or the other.
So I have been taking it semi easy on it and thinking about a replacement. If you kept up with my LS swap you noticed that I cant leave shit alone or do it like everyone else does.
My thoughts are going to a Ford 9". I realize it may not be "quite" as strong as a 14b but if anything its damn close. There is some solid weight savings there and dropping the 3rd member is cake for work or maintenance. I can also get center housing sections from just about any rear end fab place made for ford 9 and weld on whatever tubes and brackets I want.
One thing I have always heard is that you cant do high pinion rear without running the gears on the coast side. I did find this though and I know these folks have been around for a hot minute. Thoughts? I would love to be able to run high pinion rear with the short wheelbase that I have and the engine trans setup being longer than stock. My rear driveshaft is hurting for angle right now.

Next is where I will leave you scratching your heads as I want to do a rear steer setup if for no other reason just to show off. I am not looking for info on how to pull off getting the actual steering setup done but more so what components axle wise would I be looking for. I can basically have any C or knuckle setup I wish if I am building the housing up from parts.
Who makes custom length shafts for an application like that? Remember the rear center section would be centered and that eliminates picking up off the shelf front shafts to use. Will a jointed shaft for steering be able to hold up to the power? Should I be looking at RCV's?
I am obviously going to need some extra width on the axle for steering so what should I be looking for here? I can limit the steering travel with the ram and dial that in as needed.
I will have more questions as it goes.
