I think the idea is to filter it out (which is also not easy) but then this gives you a way to destroy the concentrated pfas left behind. Because otherwise what are you supposed to do with the material you have filtered out? It’d be cool if regulations required the cost of destroying pfas be added to the sale of pfas which might help manufacturers decide that they don’t need to add pfas to disposable things like paper plates after all.
so if you try to replace this yourself it turns out you have to jack up BOTH SIDES or the sway bar will be under tension and it will be hard to pull the link out. You can raise or lower the opposite side a bit to get it just right. the dudes on youtube that have a lift might not even think about how the car needs to be lifted evenly. I use arch btw.
