Jeep kj 2005 front diff leak and noise

On my jeep as of recently this winter I threw it onto 4 wheel because of some snow we got. Turning it into 4 wheel has no issue linkage checked ofc all good. After thrown into 4 and taking a left turn I hear a big pop or thunk noise and continued to drive it as it went away. Driving still any turn I took it was still popping up then sometimes in 2wd going straight or turning. I did some research and replaced the cv intermediate shaft and cv axle as it was a common source of such issues and noise and still I was hearing it. Today, I got down and jacked it up and saw what appears to be diff fluid and I have read up on some things about seals and a bearing that is in the axle connecting to the diff is there anything else I should look for and a way to get that seal and bearing if that's the case

I attached pictures on passenger cv axle there is a shaft labeled 24 in picture then bearing labeled 22 and seal labeled 21 as far as I have been able to research up on it today it seems the bearing and seal is bad cause the noise and leak but haven't found anything else on it.

If your Jeep is 2005 or later the "bearing" is actually more of a plastic bushing. It can be replaced with the needle bearing that comes in the earlier models. Inspect your cv splines that plug into the diff while everything is apart.

Pop the diff cover off and have a good look, you may have some damage on the gear teeth.

I just tore it apart this morning and saw that it wasn't a needle bearing but as you said it's OK to pull that out and just pop in the needle and new seal? And I check diff fluid and inside no metal shavings or any of the sort

Glad to hear there's no metal in there. Yes the plastic can be replaced with the needle bearing.
