Hello all, Thanks for all the wheel bearing advice I've been taking off your site lately. I've been reading this forum since my long waiting list experience in 2004, and you've never steered me wrong. For the first time since I bought by 2004 Prius, I took it back to the dealership where I bought it. It was time for the 60,000 mile service, and I also wanted them to perform a couple recalls (accelerator and water pump) and look at a couple other nits I had. (For the curious: sticky/obstructed shift knob, and found the answer here; plus intermittent caution light when starting the car after having the car in IG-ON, which we couldn't replicate.) My car, I'm told, passed the computerized tests. Every possible check box in the green/good column was checked, including the one about the wheel bearing. As soon as I drove away from the dealership, I noticed a faint, new mechanical stutter or beeping sound. It sounded like something that spins was squeaking. I'd never heard it before. It was coming from behind the dash on the driver's side. I reported the problem and took my car back to the dealership the very next day (today). A friendly technician went out with me and he quickly and confidently identified the sound as a wheel bearing going bad. Seemed like a good guy. He showed me the cupping on the left front tire, which isn't there on the right front. I got a quote of $540 for the part plus the 3 hours of labor to fix it. Everyone was very courteous and professional. But here's what I find very odd: * That left front tire with the cupping was supposed to have been rotated with the 60,000 mile service. At least, that rotation appears on my bill. Why was the cupped tire in left front? I had the wherewithal to ask about this while I was there, and their reply was that any wheel could start cupping when one wheel bearing starts to go. * That noise I'm hearing was definitely not occurring when I dropped the car off. Today I was sneaky and had my wife drive my car to the store. She wanted to know what the new sound was less than 1/2 mile from home. I conclude that the sound is indeed new. What could have occurred at the dealership to create the sound, if not the problem itself? * How did my car pass these tests with something pretty calamitous on the horizon? I also would have expected them to want to sell me a new rear wiper (which is detaching) and a new cabin air filter (which was last replaced at 30K). So, PriusChat Community, what say you? I'm a budding DIY'er, (and a huge tightwad) but this repair seems beyond me. Should I ever let this dealership work on my car again? Is this all just coincidence? Thanks much.
