Theres a Squicky/grinding noise like not rlly grinding but slight grinding noise in my truck it sounds like the front axel or the transfer case but i just put new fluid in the transfer case and the front axel isnt leaking so i dont beleive its the fluid it just started happening today

 

Sounds like you have an axle joint going out. With the truck in 2wd, check the u-joints in the front axle shafts for play. They usually squeek and grind when they're going bad.

 

I forgot to say, when i got the truck a week ago the 4x4 was unhooked the vacum hoises near the transfer case were unhooked so i hooked them back up and it started making the noise so i unhooked them but the noise stayed when i hooked them up i never put it in 4x4 or anything it just started making the noise

 

You got screwed when you bought the truck then. I'd go after whoever you bought it from. Doubt you'll get anywhere, but they were obviously hiding a pre-existing problem. You could probably take them to small claims court and get them to pay for the repair if you really wanted to push it.

From this new information it sounds like your CAD (Center Axle Disconnect) is most likely screwed up. I bet there's something busted or worn in there. It's either that or something in the t-case, but I doubt it's that... Most likely the CAD.

 

it would still make noise even if im not in 4x4? because it is this ****ing sucks lol

 

I fixed it, one of my vacum hoses were broken and the original owner unhooked them, well we hooked them back in just so we knew where they went and we knew there was 1 busted line anyhow somehow the vacum got engaged and locked my right hub anyhow i fixed the broken line and stuff put it in 4 wheel then took it out and it stoped making the noise but when im in 4 wheel it makes the noise im thinking that since the guy never used 4x4 its just no grease in the hub could i be right or is it something else?

 

grease your U-joints, especially the right one (that was engaged on accident earlier and making noise)

 

First of all, axle joints are not greaseable. Second, you don't just engage one side. When your CAD engages, it enables the whole system. I doubt it's from lack of lubrication. The inner axle shaft is always turning, even in 2wd, which lubricates everything in the front end. Your CAD just engages the outer shaft on the right side. This could be a LOT of things. But since it first started happening when you first hooked up the vacuum to the CAD, I'd check there first.

 

I found out the problem of the noise now, i think and im pretty sure its the front right u-joint on the axel going to the right tire it can be moved a little by hand and thats not good i also think there is no grease in them so im gunna change both of them and see wat happens
