Everytime the tire rotates there is a grinding or scraping noise. It is very hard to tell where it's coming from I think it is the front. I can really hear it if I let off gas around 25mph. Rear end was just rebuilt with trulock and the e brake has not worked since I have had it. Mostly I am just worried that it might have something to do with the mechanic shop that rebuilt the rear end. I am really hoping that it is not something serious I have been driving it for a while and the noise has not gotten louder. Any ideas?
