I just raised my car back to stock, but now it is making a clanching noise in the back as if someone is tapping under my car. I only does it when I am driving slow and driving over little bumps and flaws in the road. I know it isn't the shocks or springs because when I go over a speed bump they don't make any noise. Not sure what it is, I jacked up the car and tight all the nuts and bolts in the rear. So i give up trying to figure it out. Don't feel like taking it to a shop.

Thanks!
