Got the stang back from the shop having the front springs replaced. The ride is great, height is perfect, but it makes racket now when I hit bumps. Before the change it was quiet (except for the scraping noise of my tires hitting the fender!!). It sounds like a metal to metal clanking sound. I got underneath and yanked on everything possible and nothing seems loose. Before I take it back to the shop, does this sound normal or is there anything else I can check?
