Sorry everyone for the lack of updates. Work is kinda slow on the Explorer, but progress is being made and things are being well thought out.
I was able to get a Dana 44 from a 77.5 F-250. This axle is high pinion, has a 4.09:1 gear ratio (which means I don't have to get a new carrier for lower gears), flattop knuckles, disc brakes and an 8 lug bolt pattern. Condition is very good, the gears are beautiful, there is no rust/chips/shavings inside. The outside covered in years of oil which protected it pretty well from rust. Nothing more than surface rust anywhere. I've started tearing it down and will be replacing the seals, bearings, hubs, rotors and brake calipers.
I've decided to run a Dana 60 in the rear. Just waiting for a good deal on one, there's plenty to do so I'm not in a rush to pay too much.
I believe I will run a 5.13:1 gear ratio. Traction devices are yet to be determined.
For now I will keep the 4.0L and the A4LD. I traded the rear window for a Borg Warner 1354 manual transfer case. The plan is to use this case and the electric 1354 in the Explorer to make a doubler similiar to this one;

A 3-link front suspension looks to be about the best choice for this rig. I seroisly looked at the possibility of running airbags but the large diameter just makes it difficult to find locations to mount link attachments and shocks. Also I want to run wheels with a deep backspacing to reduce my width as much as possible. I will be leaving the axles full width. I'm still consider coilovers, but will likely go with shocks/coil springs for the low price.
In the rear I'm going to try reversing the main leaf. This would move the rear axle five inches rearward. This way I won't have to cut into my rear doors for clearance. I'd like to run only as much lift as I need and cut the body where I need clearance. (Keep it lower, more stable) I will likely have about 7 inches of lift and a wheelbase of around 120 inches. I am planning to run a tire in the range of 36-38 inches.
I also stripped out all the wires that I won't be needing from the back of the vehicle up to the firewall. (This includes all the wires from the power windows, rear wiper, defroster, interior lights, etc...) All that is left is the wiring for the tailights, door locks and speakers.
The body has been roughly sanded; it won't get a final paintjob till I finish all the body work including finishing the tailgate, replacing the rocker panels, and cutting the fenders.
That's about all I can think of now, I'll try to update this thread more often for everyone too (I kinda forgot about it). I won't post an update every time I turn a bolt, but whenever I get somthing cool done.
