Does anyone know how to remove this sturdy but unusual looking plastic fastener? It is found inside the wheel well holding the plastic liners to the car body. I wanted to remove the plastic liners to see what's underneath before attempting to apply some sound insulation material in there.
Some of those fasteners are a one time use and this might be one of them. Best to order a couple of replacements before: https://www.hyundaipartsdeal.com/genuine/hyundai-guard-assy-front-wheel-rh~86812-k4000.html?Make=Hyundai&Model=Kona+Electric&Year=2019&Submodel=&Filter=()&Location=trim/wheel_gaurd,,86812 and investigate the operation before dismantling the originals (part #s 1042AA and 1043EA both at .39 cents each)
No doubt it was designed to snap on during assembly but the hex suggests that it can be unscrewed to remove.
It's a push-on the first time it gets installed, although it can be snugged up by a little turning afterward. Since it usually goes onto a threaded stud, you *should* be able to unscrew it -- and if you're careful you won't mangle its innards. It's not strictly threads inside, more like a bunch of flexible plastic vanes that grip whatever goes through, but will sort of behave like threads if you're careful. If the stud isn't threaded but has a lot of parallel ridges like a ring-shank nail, then you're stuck with just pulling it. But I doubt you'll find that. _H*
