I've had a problem for several years where anytime I would go between say 10-20 mph over small bumps etc...I would hear a click/clak clunking type noise from the front left area. I first thought it was the steering rack but last night I had the car up on a lift and grabbed my front sway bar on the left side and I heard the infamous clunk/clak as I wiggled it up and down. Sway bar end link was bad. Replaced both sides with more solid than stock Moog's ($30 a piece / Lifetime warranty) that have grease fittings on the joints. No more noises.
