I did something similar with delrin and steel inserts in a jeep I had, and it worked out. You’re looking at a lot more money, but jeep guys do it. Look at those forums, see their mileage, and cut it in half if you see so much as a gravel road.
The real question is if you want to build something or have something. how much is your time worth welding it up while you build these? Could you work a couple hrs OT and pay for something already available? If it’s a hobby/beer drinking thing, I get it. If you’re trying to get a problem fixed, it’s rarely worth it unless you want to market your fix.
