Cj TRANSFER CASE making a clicking/grinding noise when moving

VIDEO OF THE NOISE:

Hey guys, I have 1977 Jeep CJ7 with a DANA 300 t-case and a T150 tranny. Just finished swapping in a 304 and took it out for a test drive and heard a grinding noise coming from what i thought was the tranny, so I changed the fluid and the noise went away in 2wd only, so I knew it was a t-case problem. Then it started grinding in 2hi as well as 4hi and 4lo. I changed the t-case fluid and it came out a a light brown color, but didnt look too bad, also no metal flakes and rubbed my finger in it with no grit.

So I am assuming its not internal since there is no metal in the gear oil?

I checked the u-joints and they seem okay, but i honestly dont know how to inspect them that well other then them having a cap falling off or something obvious. Linkage is pretty loose a lot of play in the T-case lever when in gear so maybe thats it? goes into gear pretty easy though if im moving.


Also I put the t-case in neutral and ran it through the gears with no noise so I know its not the tranny.

Any help would be appreciated!!!!!

It's probably a dana 20 t-case on the back of the T-150.

You could probably drop the pan off the t-case for a visual inspection.

I've heard a similar sound like when I wasn't fully in engaged in one range or the other.

Ok, yea it probably is.

So what would be causing it to not be fully engaged? Could it be a hub issue, I had the passenger one of recently to do a u-joint up front, and realized i never even put in 4wd after that to test it, maybe i re-assembled it wrong?

I appreciate the quick response
