Anytime I hit a small pothole or bump on the road my Drivers side suspension makes a click sound right as I hit it. Just one click per bump. I could go all day without hearing it...but typically I hit a few bumps and I hear it. Boy is it annoying. Started after I came back from a day trip offroading.
Could be a lot of things. How loud is it? Have you checked your swaybar links? I know when mine was going out it would make a click / pop noise when I hit bumps. Get under it, grab things and start shaking them
