Recently as i was looking into portal axle of G63, I stumbled upon an interesting company I never heard of before called Werewolf from Ukraine. They have portal axles for Jeep, Bronco, Tacoma, G Class and many other models. I liked their youtube channel and the company seems legit. I recently contacted them about 5th gen 4runner option and they said they can make it no problem. The price seems spot on and very good considering what it is. I am not sure how the logistics will work out to ship it to the US with what is going on right now.
This is their recent video showing an installation on Prado

This is their website

In the description it says Models which the kit fits bolt-on:
Tacoma, Hilux, 4Runner, Fortuner, FJ Cruiser, Prado 120/150 and Lexus GX.
Right now I am not in the position to buy it and make it happen as I am not an expert on this stuff. But I thought I would share this with the community in case someone with more time and interest can look further into this. Would love to see someone setting this up on the 5th gen 4Runner back in the states. If the war was not going on, I would have driven over there in a heart beat and have it installed right away. I am actually living in the Balkans right now, not too far of a drive in my 2016 4Runner.
Disclaimer, I have no association with this business, just wanted share.
Update After digging more: It looks like they have dealers in Calgary as well and they do worldwide shipping.
