What will happen if I don't replace worn shocks or struts?

Shocks and struts are an integral part of your suspension system. They work to prevent suspension parts and tyres from wearing out prematurely. If worn, they could jeopardize your ability to stop, steer and maintain stability. They also work to maintain tyre contact with the road and reduce the rate at which vehicle weight transfers among the wheels when negotiating corners or during braking.
