For 2 weeks I've heard a knock from the passenger side so I changed the stabilizer bar but the problem persists so I'm checking the ball joints and a few other things but they look good, i check the spring too, but they look good too. One day while driving I heard a loud noise like something was broken and when I checked the top of the strut just broke. Incidentally, the KYB has a stiffer, less smooth ride than a motorcycle, and your focus moves 1.5 inches higher.
