My first time tackling this job myself: replacing all four sway bar endlinks on the Miata, front and rear. The old ones had seen better days — cracked boots, more play than I'd like, and the kind of clunk over bumps that makes you assume something worse is wrong before you actually look underneath.
What I figured would be a quick job turned into most of an afternoon — wrong socket, a seized bolt, and more time spent looking things up than actually turning wrenches. But the clunk's gone, and I came away knowing a lot more about the suspension than I expected to.
