BW4406 clearance

[shr3dd3r 09]

Okay, so I am about to begin tearing my 5.0 mountaineer apart tomorrow in preparation for my swap and I have one final concern. I've heard about all the clearance issues with using a bw4406 in a ranger, but as far as I know they still fit it's just pretty tight.

What I want to know is if there is any difference in clearance between a regular cab ranger and a super cab with respect to the gas tank (The regular cabs have a smaller tank, but I don't know if it makes up for the difference in length) I am using an m5r2 as well.

I know the bw4406 is huge, but I have one laying around and I would like to use it if I can. It's hard for me to estimate how far back it will sit considering I'm using a new engine, trans, and t-case. As it sits my 1354 is about 5" from the gas tank.

So, having said that... will a bw4406 fit under a regular cab ranger, and if so can you direct me to any posts where this has been done?

I seriously doubt that the 4406 will drop right into a regular cab using a stock tank. It's a tight enough fit in a Supercab that has an extra 14" of wheelbase.

In the event that it does not fit once I get the engine and trans in, do you know of any other t-cases I could stuff under there in a regular cab? I don't want to lose 4X4 if I don't have to. I could use my current t-case with an adapter I think, but it costs more than a separate full size t-case does. Any suggestions? I don't know how large other t-cases are in comparison to my own or the bw4406...

Some use an np208 and a np205. The 208 has a slip yoke rear and is said to spill fluid when removed. The 205 is small but very heavy and has a kind of a crap gearing, its like 1.96:1.

I don't know how large a bw4406 is, but from what I've read, an np205 is about 12 1/2 inches from mounting surface to rear out. It has a 1.96:1 low ratio, though.

Also, if you plan on using an m5od-r2, http://www.explorerforum.com/forums/showthread.php?p=2232819 this page has tons of useful information on putting one behind a 302 in a 98 explorer.

I think you mean np205, not 203. The 203 is only good for stealing the range box off of to build a doubler.

I did, thanks for pointing it out

I've read through that post thoroughly already, which is why I feel good about using an m5r2. The procedure should be the same. I have plenty of electrical knowledge to handle the wiring if there are any differences.

I'll just have to wait and see what kind of room I have once I get the engine and trans in. Hopefully the bw4406 will fit since I already have it, but if not I'll look into the np205 and 208.

The Bronco 208 has a fixed output. The 208 is a little less involved than a 205 but each have pros and cons. 208 will use a more modern linkage which the ranger one will normally work and the case will fit the trans with no issue. You may have to trim some tabs off maybe shave the lower edge of the frame depending on your engine/trans placement. The 205 will fit no problems physically. You will have to add a mount on the driver side being that its heavy and notch the tailhousing to clear the shift rail. The linkage is kinda funky unless you twin stick it.

From what I read, the Broncos have a different style bolt pattern for the transfers cases then the trucks do. Now you can put a fixed yoke off the gm or dodge ones on a good, but that's easier said than done, but plenty of articles online on how to do it.

I'm currently running an np208 on my setup and have no problems with having a slip yoke. But I have seen and you can buy a yoke that will convert your slip yoke into a flange fitting by drilling a hole and tapping your output shaft for a bolt too hold the flange.

Thats only on the early Bronco T-case (Dana 20).

Exactly correct. I don't even mention a dana 20 anymore unless somone is hell bent on using it. Great case but unless you have a complete EB with a C4 laying around for parts you will have some big cash in buying parts. Every full size Bronco NP208 is supposed to have a fixed yoke unless some clown swapped it otherwise.
