I noticed whistling or at times high-pitched squeaky noises for a little over a week while driving. It didn't matter what speeds I was driving at. I paid for a diagnostic at my local Firestone on Sunday, and the problems diagnosed were front wheel bearing and CV boots leaking oil. Firestone quoted me a ridiculous price for the repairs, so I tried going to a local auto shop to confirm whether or not the diagnostic I got from Firestone is accurate. The auto shop I went to the very next day on Monday was able to diagnose the same issues with a test drive only. Today, Tuesday morning, while I was on my way to work, I still heard the whistling noises while driving. However, after work, while driving, I don’t notice the whistling noises anymore. To note, I got all four of my wheels changed just four weeks ago, and this problem occurred less than 2 weeks ago.
Could this really be a wheel bearing issue? Since I am not hearing a whistling noise now, is the wheel bearing no longer an issue? Could it have been new tires adjusting to the road? I am now confused after this sound seems to have gone away since this afternoon after almost 2 weeks.
