About a week ago, I was working on the supe, and put some of my weight on the front nose, the car went down a little, and as this happened, I heard a kind of scraping/rubbing noise come from the driver's side shock... Then earlier tonight, i tried it again, and now there isn't any noise really, but when you try to bounce it, it will go down, then come back to normal height slowly and stay there.. I'm guessing the strut is bad? Is it safe to drive like this?
