The Quest continues...
Hi Everyone,
Rather than bumping an old thread I decided to start a new one. As some of you may recall, I have acquired the partial '99 Explorer that I want to use the rolling chassis from under my '53 F-100. There is so much advantage to doing this for my application that I don't even want to consider an alternative. Everything just sort of fits into place for me except one minor problem. It was my intention to go with a manual hub conversion and now it seems that there is no such thing, or at least I haven't found it yet.
Our '95 Explorer and the partial '99 are very similar but not the same. The front diff on the '95 has a servo or actuator on it to engage and dis-engage it. The Front diff on the '99 does not have the actuator and is locked in all the time. I made the mistake of assuming that the '99 was identical to the '95. I had looked at others and never noticed the difference. Apparently Ford did something different with the transfer case that made it so it did not matter if the front drive shaft was turning all the time. I am committed to doing this project with this chassis, so I won't be waiting around for locking hubs. Probably the only set back I'll suffer is gas mileage and given that this thing will be running a 351-W with a cam and a four bbl. carb, MPG is probably a moot point anyway. With a manual truck 4sp. and manual transfer case I doubt if it will hurt anything to run with the front drive shaft turning all the time. The only other alternative I can think of would be some kind of in&out box on the front shaft. I don't know off hand what I could use for that or if there is room to put one in.
I took this to the Explorer forum but it seems there are only drivers there and no builders or mechanics because the respones was zilch. I have yet to tear into the hubs on the '99 but from all appearances it looks as though the set up looks to be pretty much the same as a front wheel drive car except a little heavier duty. If that is the case It may not be possible to adapt a hub conversion without a lot of different parts being substituted like floating spindles.
When I was in the Air Force back in the mid 60's we had a bunch of crew cab Dodge power wagons and none of them had locking hubs. The Air Force decided we didn't need 4WD so they took all the front drive shafts out. Go figure...

A '99 Explorer could have two different T-cases. B-W 44-04 or 44-05.
The 44-04 is an all wheel drive and has no external controls. Torque is divided between the front and rear.
The 44-05 is a full time 4 wheel drive. It has A4WD (automatic), 4WD High and 4WD Low.
In A4WD there are two speed sensors that monitor the driveshaft speeds and when they differ by a certain amount the module activates an internal clutch to lock the transfer case and equalize d-shaft speeds.
If you were to (un lock) the hubs the t-case would engage the front d-shaft as it would think the rear wheels were spinning the front was not.
Hope this helps some.

I'm just using the rolling chassis with the front and rear diffs. The Explorer engine, tranny and transfer case are gone. They will not be used in this project. Manual hubs are desirable but not necessary for what I'm doing. I'm now pretty sure that no one offers a conversion kit as floating spindles would be required, thus making it an expensive proposition.

I'm with you now.
I must have missed part of the explanation. I will go back and reread it as I am curious to what you are using for the power train. It sounds like an interesting build. Have fun with it.
