I have an 07 Santa Fe with 50K miles. I have some clunking going on both sides. I am thinking either the lower control arm or both bushings are bad on the struts. Has anyone had similar issues at this mileage? I may replace the struts as I seem to feel they are a bit "mushy" and I prefer a firmer ride. Does anyone make a heavy duty strut for our cars like a Rancho 5000?
