Re: High-Pitched Tuning Fork Noise
Sorry to bring up an old thread, but for what it's worth we've been dealing with this issue for a while now. We are on our second power steering pump, and the noise is back. It did go away for a while (after they replaced it), but returned after about 800 miles. Interestingly enough, I noticed that there was almost no power steering fluid in the reservoir not too long ago.... Went back to dealer, thinking perhaps the real issue was now discovered. Dealer acknowledged the lack of fluid (was alarmed by it) and claimed it was an air bubble in the system. Removed the bubble, topped off the fluid, and claimed that the whistle was once again resolved along with it. It wasn't. Still there... so we may be heading for pump #3 at some point. Or living with it... doesn't really cause issues with driving, it's just annoying, as you guys that hear/have it know.
