Only get "Clunk" when shifting in 4HI

[HustleHard]

So I know there a tons of threads about the driveline clunk that our 4runners have, but I haven't seen anything mentioned about this. I only get the clunk when I'm in 4HI (my 4LO is seized so cant test that one out). When I'm in 2WD, there's no issue at all. Is this normal for everyone?

There is a slip yoke on the front of the t-case as well, it's likely under-greased. Make sure to use a moly grease, and hit the rest of the front zerks with MP grease while you're under there.

Also, when was the last time the front diff and t-case oils were changed? I had a small clunk in 4hi in my 3rd gen (also multimode) but a little extra grease took care of it.
