Don't think I hear a clicking sound but I do hear a squeak from the rear when I enter the car. Mr. Albundy, can bad bushings and pitman arm make your tires hum or drone at a certain speed like 80KPH for example? My Dunlop SP9000 is now totally wasted and so I bought a pair of used 50% thread Falken GR-B and Potenza S01. Both thread patterns look identical although different brand. Oem? Anyway, these tires start to hum at exactly 80KPH and will hum at any speed on some surfaces. Is this normal for these types of tires or is the bad bushings and pitman arm causing the tires to sing?</blockquote>
