question about transfer case
ok here it is. i am fairly certain that the noise comming from my truck is comming from the t case. the cost of a new or rebuilt t case is way to steep right a round a grand, 700+ core charge and i dont have that kind of cash. i can pick up a 97 parts truck with a good t case for 350. (mine is also a 97) here is my question. i have the shift on the dash 4x4 but i dont know what this parts truck has and i am worried that it will have the manual shift. is it possible to use the manual shift in my truck, but set it up with the switch on the dash? is it as simple as installing the shift motor from my t case onto the manual shift t case or will this simply not work?? thanks to any input.
how hard is it to rebuild a t case? i have never done something like that and have no clue what i would be getting into. if it wasnt all that difficult i could do that my self and save some money. but again i just dont know.

well in mt opinion if it is a manuel transfer case but the exact same one you have now it should just be as easy as swapping the electric shifter. if not its not hard to just cut a hole it the floor board for the stick, but im sure you dont wana do that. they are bound to make a kit you could buy that could convert it to electric if they dont match.
as for rebuilding it, i tried to rebuild a np205 tranfercase on my 79 f-250, and it was extremly dificult. i saw them do it on trucks and xtreem 4x4 but they are pros. so i took mine to a local shop and had it done for 75 bucks.

i am glad to hear that you got it rebuilt for so cheap. i hadnt yet looked into that (and cant since i wont be home for another week and a half) but that was my original intention was to pull it myself and take it in. all i know for sure though is that the tail shaft comming out of the t case has about a half an inch or so of play front to back. wich i think is the noise i hear. the t case stilll functions though (i can still sling mud). but if i jack the truck up and have some one turn the drive train by hand i can chase a squeak to the area of the t case. so i think im driving a ticking time bomb. and it needs to last 130 miles before i can get it fixed. thanks for the imput. that has lifted my spirits hearing i MIGHT get it done for less than 100 bucks.

yea i dont think its to expensive. the tailshaft should always have some play for your suspension to flex and not break u-joints or bend anything. you might try to change your t-case fluid, somtimes it could be just bad lubrication on the gears that makes some noise, cheap idea probly wont hurt anything. if you do or done already, i would get sum royal purple synthetic gear fluid, i put some in mine and it helps alot.

well i checked what was in it and it seemed ok but who knows. i may try the royal purple. ive heard great things but never had the chance to try it. i can understand some play in it, but it kinda seemed ecessive (sp?) especially since the drive shaft has i wanna say 3 or 4 inches worth of travel on the shaft. but this side of any 4x4 is kinda new to me.

When I had my 97, It had a LOT of play in the driveshaft. enough play to make a hell of a noise when you went over a bump like while braking coming of the interstate! If i'm not mistaken, there was a TSB out about this. If you have time, i would drop the driveshaft and clean and regrease the splines. You really have to beat the t-case up pretty bad in order to have issues. Do you do a lot of off-roading?

well i do enjoy the occasional romp through the empty bean field or drivin through the woods to get this years buck.lol but nothing that extreem and not very often. i noticed the sound on a trip back to school one sunday evening going down the high way so i have know idea when it really started. but i replaced the u joints and re greased the splines when i put it all back to gether. and there is no play or noise in the rear end. also this truck has seen more high way miles in the last four months than it has probably seen in the last 2 or 3 years. oh and its all origional and ive only had it since the begining of august.

You could take the shifter off of your t-case and put it on the other one, you'll have to disassemble both of them to do it, it would still be cheaper than a new t-case or a rebuild of the one you have. Keep in mind that the 4406 you have is a modern, shift on the fly engineering marvel with viscous couplers and synchroes, and the NP205 is a piece of 1950's era cast iron agricultural equipment.
Do not put gear oil in that t-case. either. Synthetic ATF only or you'll fry every synchro that thing has.
Here's a nice exploded diagram of a 4406 t-case for you.

wooowwwww
lol id rather stay away from that. . . . looks like something i could mess up and id rather not do that. how much do you suppose it would cost to have done? i can get a bit of a discount because i know some people at the shop and im going to pull some strings, but still id like to stay south of 300 bucks. and since ive had a transmition done for 600, i would think that would be be possible. and yes i know location is going to make a difference, but id appriciate it i could get maybe a ballpark.

The best thing you can do is just take the t-case to the shop and talk to them. Most of the time 4406's don't actually need a lot of parts to repair them, they're very good reliable t-cases. It's really tough to estimate actual costs without being able to see it.
