My 2005 Altima SE R makes I click/knocking/popping/cracking (whatever you wanna call it) noise when I go over bumps or bump off camber at speeds under 15mph. Or when backing out of driveway over little hump. What could that be? Took to nissan dealership and they said it was front stuts. Did online research and might be sway bar links (says it's more common) What is it? How to fix? Thanks, Nick
