moody transfercase
Hello fellow Ford guys, I am a newbie to this forum and would appreciate some help with my np208 tranfercase. When ever it feels like it it just pops out of 4 wheel drive. If I back off the throttle once in a while it seems to stay in 4 wheel ok. If someone out there can help I would really appreciate it.

You know there are a lot of reasons you'd feel like this transfer case pops in and out of 4WD. The chain has a problem with wear and stetching this could lead to a popping and slapping noise. The fact it uses an aluminum case can lead to wear around the bearings thereby giving you slack in some components. The design is ok, but not particularly bullet proof. My first experience with one was having to rebuild mine because the thrust washer ate through the shift fork and would try to engage itself into 4HI a month after buying it with 93,000 miles.
I think you may want to drop the 208 out of the vehicle and pull it apart (not for the faint at heart) or take it to a tranny or 4x4 shop. From my experience there are too many variables to give you a definite answer without driving the vehicle myself. A bonus from this is you get to see how things are built
Hopefully someone with some beneficial knowledge will answer your post.

I kind of figured it would come down to tearing it apart, i was just hoping that before I did I would have an idea of what may be wrong.
As a side note there is no noise from the case it simply shifts out of 4 wheel drive until I back off the throttle and it engages again.
I do apreciate the time you took to answer my post.

[updated:LAST EDITED ON 13-Mar-02 AT 00:10 AM (EST)]well i had a chance and looked at mine tonight. i would say that maybe some parts are worn with how it engages and disengages the 4x4. look and see if the floor shifter moves when it engages and disengages. if it doesnt then there might be a broken shaft or some splines that are stripped out. thats bout the best thing i can come up with without seeing it. hope that helps.

[updated:LAST EDITED ON 13-Mar-02 AT 12:22 PM (EST)]Thanks for all the help guys, this is the best forum I have found to date.
Oh by the way how easy are these to rebuild, I have done engines, rear ends auto and man trans, and are there any special tools that I would need? Thanks again.

One question. Does your truck have a body lift?
If it does, it could be the shifter hitting the floorpan.
Just something else to look at.

It definitely helps to have an extra set of hands 
.
You'll need somebody to help you realign the shafts when you get ready to put it back together. I don't recall any special tools. An arbor press is helpful for the bearings.
You might want to spring for the manual or go to your library and see if they have the service manual for Ford Light Duty Trucks for that year. I wish I would have done mine with the manual. I could have checked for the play tolerances in the shafts and chain. I didn't and I think I needed to put some shims in the tighten it up. Mine is still pretty sloppy, but it works.

I was assuming that he'd have help with brains
. Then again, those brains can be a pretty expensive option for some...
Just watch yourselves, the edges on the aluminum casting are pretty sharp. I wore mechanics gloves, but that doesn't save you from the occasional drop.
