thanks. yeah likely will do the alt pulley in a couple weeks. thanks for the step-by-step!This just happened to my 2009. It is the alternator clutch pully. 1. Remove negative battery terminal. 2. Remove passenger front tire. 3. Remove all the plastic guards. 4. unbolt ac compressor let hang. 5. unbolt alternator and angle downward toward wheel well. 6. pull off pulley covering. 7. use 17mm hex drive on impact wrench ccw to spin off pulley. 8. Install new one with impact wrench cw.
I did end up replacing the tensioner assembly, both idlers, and put a new belt on it for good measure.
