Petty's Rear Strut Brace - Help me diagnose a rattle
Hello y'all, installed the petty's garage rear strut brace a few days ago and have been troubleshooting a rattle on the drivers side (rear of course). I have the brace installed correctly after viewing several threads on here and youtube videos because the pics in the instructions that came with the brace were not sufficient. Each nut has been torqued per instructions, there were no noticeable loose parts and the mounts sit flush on the shock mounts. i attempted to muscle the brace to see what is rattling but it is solid as a rock as it sits. The rattle is definitely on the drivers side.
In the process of troubleshooting i removed only the drivers side cups, washers and nuts and drove around and now the car is quiet as stock, so there has to be something with the hardware i would think. After removing the hardware several times i have damaged the threads (sits above where the nut is tightened all the way down so should not be a loose nut) so will be chasing those threads to clean it up and will get new lock nuts, in the meantime the drivers side mount is not bolted down and there is no noise whatsoever.
Does anyone have any similar experiences and if so what did you do to fix it? Thanks in advance!
