Ok I am going to tag on here. I have a Vantopia decoupler bough a few years ago. It leaked, and I thought it was my fault for damaging the seal before installing it. I just had my gearbox rebuilt at Rancho, they replaced the seal, and lo and behold it leaks immediately. I can’t tolerate drips, sorry.
I kinda feel like the design is such that the dowel pin hole goes right through the seal during actuation. How would that even seal if so? It would have to pull the actuator off and try to actuate by hand, to really know, which I could do. Is this common or unique to Vantopia? Seems like a longer servo bracket would be best, along with a longer shaft. Thoughts?
Not keen on dropping another $1.5k on another one that leaks. Actuation has been fine, and lots of fun off road in sand, snow. Very happy otherwise.

On mine, you can see that someone extended a short bracket to be the same length as a longer bracket because there are two lengths of shafts that go into the transmission.
So, I suspect you have a short bracket which plunges the shaft further than it needs to go and you need a taller bracket.
You may want to contact vantopia and confirm they sent the right bracket...
