So outdrive ? Around the cup?

No literally inside the diff cup.
Not an Arrma but look inside the diff cup and you will see an oring in there.

Bingo! Ok so under the sun gear got it I’m actually done and ran it yesterday now back to taking apart

@SrC figured it out lol I’m an idiot I should of ask when I had the apart!

Let me ask you this is the rea diff supposed to to be limited slip and the front?

Rear should have the least amount of LSD staging. Fronts, the most if anything. But many also shim the rear EXB diff to be "OPEN' with good results.
But much is personal taste.

I've used o-ring there also at times. Even for the center Drive shafts at times. Helps with Driveline oscillation.

Apparently EXB diff O-rings are Black. And described as silicone O-rings.
