Long story short, store sold me a GTI sway bar by mistake and now its been grinding against the driveshaft front coupling. Good news is they are going to be replacing it with the correct sway bar for free along with installation but I am worried about the damage to the coupling. I am requesting them to replace it as well but in the meantime should I be worried about this part? I dont want it to grind through but I need to drive the car to commute for work. I dont know the internal thickness of this metal outer ring to know if I should be worried about me basically grinding off a loose metal ring if it goes all the way through.
