HELP! transfer case(?) noise!

Guys I REALLY REALLY REALLY need some help here!

So after a good mudbath I noticed a really odd metal on metal noise. Its kind of a grinding/squeek. Its deffinatly a rotational noise, by that i mean it is a rythmic, repetitive noise happening every time something rotates, in the same way a wheel bearing has that "whuhh-whuhh-whuhh-whuhh" albeit a TOTALLY different sound.

Ive heard a differential blow out and my noise has a hint of commanality, like ya know that grinding noise that comes from all the broken bits in the diff rattling arround? yea, its like a little tiny version of that (like there is only one piece rattling arround) with a squeek added in for an extra scarry problem.

I DONT think its a wheelbearing because with the front end in the air i can spin the tires and cant duplicate any hint of the mystery noise.

then in desperation i yanked off the skid plates for a better look arround...
heres what i found where the front driveshaft comes out of the transfer case...
i sprayed INOX into the ripped seal and the noise has all but gone away...
I'm GUESSING that the seal was bad, then i drove it through the mud, muck, and water, and totally screwed my transfer case. Im HOPING i can drain the t-case fluid, replace that seal, then fill the t-case and problem solved...

You are only going to have to spend $65. That is the cv joint. Look up driveshaftparts.com then search for it in there sorry I don't have the link I'm on my phone. It's easy to change, I'm ordering one tomorrow morning.

Yep, the boot on the CV joint is bad (common issue) and so time to replace the CV joint.

As tphitterlude92 said, it's a $65 part. Easy repair to do yourself if you're a moderate garage mechanic. There's a great how-to with pics over at JeepKJ.com.

Here's a link to the part:

I love you guys right now! Lol. I was fearing a new t-case or driveshaft. $65 I can so live with. Plus it gives me an excuse to crawl under the jeeper and get dirty!

Yes once that boot goes then dirt etc gets in there and it basically destroys the bearings which rotate all of the time so yes it would be a rotational noise
Replacing the 2nd one in mine this week, but with 172,000 I guess I can't complain
