anyone know where i can find a diagram of the 4x4 system? my hanes manuel says nothin about it and im tryin to figure out why it wont engage fully.

 

Yeah mine has some troubles engaging from time to time. It is like it I have to pull it back just right for it to engage.

 

Is it the transfercase not engaging or the axle?

 

There is a xmas thread that you might search for and a google search will turn up some articles

 

The diaphram itself cannot be purchased. You have to either find an old CAD at a junkyard and pull it apart, buy the whole CAD new, or replace it with a cable actuated posi-lok.

 

its soundin like its tryin to engage but it wont all the way. i need to get up under there tommrow and try to fix it, i just dont know where to start

 

nah not diaphram, diagram. like a map out of the 4x4 system so i can know what im lookin at.

 

There ain't much to map out.

Transfer Case - Big thing behind the transmission with 2 drive shafts coming out of it and a shifter linkage up top going into it via 2 rails.

Front axle- Very simple due to full time wheel to axle engagement (AKA no locking hubs). You have a vacuum line running to your CAD and that should be all you have to worry about without a major axle tear down.

Basically we need to answer Ice_Man's question, what isn't engaging, the t-case or the front axle? If you can pull your lever all the way back and feel it hit a little detent, then the t-case should be enaged. Are you hearing gears grind or what?

Edit: If it weren't snowing here, I would crawl under my truck and take some pics and label themfor you, but sorry, I ain'tlaying down in the snow before class...

 

If you go with the posi-lock as zique mentioned, here's a link I found that I have bookmarked for when I get mine fixed. With all of the problems with the vacuum lines that I've found on mine, I am not even going to worry about whether or not my 11 year old vacuum actuator on my front axle is still working properly since I can't really determine that until I replace all of the missing / damaged and plugged vacuum lines. I don't really need the 4wd so this project is on the back burner for now. Here's the link:

haha...sorry, I coulda swore that said diaphram when I first read it. There is a diagram on here somewhere. Do a search for CAD on here and it will come up. At least I found it when I was looking into a posi-lok earlier this year.
