My 2007 Cobalt at 31500mi out of the blue started making this horrible front-end clunk over bumps at lower speeds. I suspected maybe stabilizer bar end links having been down that road before with Chevys and Fords?? Nope, they feel tight as new? Jacked it up, got underneath as best I could, couldn't find any play or noises anywhere. Of course this was after accidentally grabbing the catalytic converter and burning the finger prints off several fingers. (scorching hot after 20sec BTW thanks to GM's air injection :!) Anyhoo.. frustrated I called the dealer I bought it from. They set me up with an appointment the next day. Long story short? Per the invoice; The front lower control arm bushings had to be replaced on both sides, plus a front end alignment. All on GMs dime. Even got shuttle rides. No fuss, no muss. Is it common for these things to go from all to nothing in one swoop? The car has always been tight and clunk free?
