Alex1978 Posted March 21 Share Posted March 21 Greetings, everyone. I am experiencing a bothersome sound under my vehicle. Upon inspecting the area beneath, I first believed it was a loose heat shield. However, I have since determined that one of the plastic undertray studs has fractured. Can a replacement be obtained? If the repair has to be done, the optimal course of action is to grind or flap the disc flat, use JB weld to secure it, and then apply an undercoat to cover it. This process concludes the repair. Are there any individuals who own the component number for the stud and plastic nut? Researched extensively but was unable to locate it. Thank you very much Quote Link to comment Share on other sites More sharing options...

bvlenci Posted March 21 Share Posted March 21 Conduct a search on eBay...Mercedes undertray screws made of plastic. There are many alternatives. Has the screw thread in your picture become detached? Quote Link to comment Share on other sites More sharing options...
Alex1978 Posted March 21 Author Share Posted March 21 Indeed, the plastic nut has been removed, and I have also seen the detachment of the stud, which is the metal component that protrudes from the floor. Quote Link to comment Share on other sites More sharing options...

carBlacken Posted March 21 Share Posted March 21 After drilling, purify the area and apply paint. The waxoyl/bilt hamber/lanoguard should be reassembled once it has dried. Quote Link to comment Share on other sites More sharing options...
Matt865 Posted March 21 Share Posted March 21 Drilling is necessary since welding is not a viable alternative. During my last visit, all the little plants received a powerful dose of copper slip. Quote Link to comment Share on other sites More sharing options...
