On a regular basis when I look at my front end the bottom of the tires are prominently sticking out. Sometimes though they look fine or the tops of the tires are out. What is causing this? The steering is also fairly loose. I dont even feel comfortable taking a turn at speed any more. There is also a tapping noise coming from each front corner when going over a bump. I also have to keep it in firm ride to keep it to a minimum. What gives?
