The site doesn't host video. The easiest way is to upload it to YouTube and then post the link here.

The dogs on the gear that engage the drive power are rounding off.

There are a lot of topics on this, and a lot of people that don't believe it happens.

How many miles? What size tires? Where do you ride?

2000 miles stock tires and hard packed trails

I have the tranny taken apart right now and didnt see anything wrong and barely any shavings

Almost sounds like two gears are trying to engage or maybe a bent shift fork.

Does it matter what gear you are in? Wish the video had you shifting 1 to 2nd to 3rd. If it is a trans gear, the frequency would shift with the gear and be silent in the gear that had the problem, been my experience on motorcycles. I seems to me from the video that your chatter is speed dependent, not rpm or clutch dependent which would point to final drive.

Also curious if switching in and out of 4x4 changed to chatter.

I just went thru a similar chatter that was solved by throwing more cv lube in all four of the rear cv's. My chatter volume increased when turning sharp on the pavement in my neighborhood, almost disappearing when going straight, and silent when on the dirt. More lube in the cv boots made chatter disappear completely.
Its does it in every gear but reverse

Noise was the same on 4x4 or not

I remember seeing a post about the trans main shaft for the gears having issues? Maybe look into that.

When the dogs wear and round it does not necessarily mean you will find stuff in the filter. You took the trans apart, do you have any pics of the gears?

This is what i discovered today when taking gears apart

You might consider installing a Quick Shift system and install one of the lighter weight flywheels.
