Not terrible. There’s one internal snap ring that is a bit of a PITA. If they had put a couple of holes in it for snap ring pliers there would be nothing to it, but they went a different route for some reason.
I have this too. Hate it, but it seems harmless and I haven't been able to track it down. I think I have it narrowed to rear t-case output but haven't looked into it much further.
