Jens04Rolla Hello to you all in Corolland. I have a problem with my 04 Corolla that has been going on for a few months now. Whenever I drive at any speed, or when I'm decelerating I hear this fast intermittent boop, boop, boop......sound coming from what sounds like the left front wheel area of the car. I took the car to Les Schwab tire and had them check out the rotors, bearings, hub assembly. Everything checked out fine, so I went to the Toyota dealership and told them about it and the tech took a drive with me and said it was road noise. I said that can't be because even on smooth pavement I hear this sound, and like I said it's a boop, boop sound not a grumble, like road noise.Later on I have some service done at the dealership and I tell them the noise is still happening and can they check the undercarriage of the vehicle to see if anything is broken or damaged. So they drove the car around and said they can't replicate the noise. To me that's dealershipspeak for "If we can't hear it, there is no problem."So I'm still driving the car around and the noise is happening much more often and now I'm feeling a sort of slight vibration when this occurs. I am very concerned and I was wondering if anyone here has any idea what could be making a noise like this. The car has only 30,500 miles on it and I have babied the heck out of it. Other people who have gone for a ride in my car have heard it also, so I'm not hearing things. Any ideas?
