i wheeled my thruck and parked it for a month for collage and when i got home some thing wasent right
anyway i was working on it and took it for a test drive around the block
when i put it in 4x4 ( high and low) it makes a bad rubbing sound
i dont think its the t-case because it stills dose it with the hubs locked but the t-case still in 2wd
i cant find it and dont know what to start pulling apart any ideas
it was fine b4 i parked it
but now its making this sound kinda like two pieces of metal rubbing togher

Dude have you checked out anything yet? Like jacked the truck up and checked for bearing play or brakes pad wear or mud or rocks stuck? Good idea to just take a look at everything and then go from there.

it doesn't do it in 2wd with the hubs unlocked?

Axle shaft U joints.

nope

its kinda a slow rub
but not conatant
when i put in in 4 i can go about 50 ft and then it starts
and its not rubbing all the time
its sounds like rub....rub....rub....rub....rub
a very small pause inbetween rubs like somthing is out of round

my money goes to a u joint or axle joint...

Hey try this,

Move the vehicle slowly forward till you hear the noise and then touch the brake pedal with your foot and see if the noise changes from rub a rub to swoosh.. Real high tek stuff.
I got to thinking that maybe with the sitting and all maybe you have a hung caliper. Not uncommon for them to expand and not retract.

If that ain't it then just turn up the stereo some more.
