For some reason or other, the bad one is the opposite from the way you're turning. If it makes a noise turning left (like mine did) it's the right bearing. Dealer charged me $81.00 for the job a couple of years ago. Hourly rates have gone up a bit since then, but I would think it would be $100 or less. Ironically, the bearing was covered by the ESP plan I had, but with the $100 deductible, the plan wasn't any help.
Oh yeah, welcome.
