I'll check out the bearings. Thank you for the suggestion.vibrologist wrote:Hi
I can't access this recording so I comment on the idea that this is rotational noise that is audible as you slow down, most likely applying the brakes. the first place to look are the wheel bearings. See if braking or not braking makes a difference. I once had a car where a failing wheel bearing only made noise under braking.
It IS me mooing. I was driving yesterday and told my wife to use her phone to record the sound. The recording didn't work out so I tried "simulating" the noise. That recording is actually pretty close. And yes, I accept the shame and ridicule one should receive for attempting this.Caretaker wrote:When I listed to your audio file, it sounded more like a gag recording of you mooing into the recorder, not something mechanical.
After using my 90 minute free time this morning to troubleshoot this further, I am thinking calipers might be it. I drove around for about 30 minutes and the noise has lessened even more today, to the point I don't think a mechanic would even hear it. It was raining out so not a great day for it as rain tends to make my rattly vibe sound much better. I took tires back off to take a more thorough look at things and to get a better look at the cv boot condition, all intact and no grease anywhere. Struts seem ok. Check the bearings again while warm and still no play or noise.vibrologist wrote:Check if the brakes are dragging a little. Sticky sliders in the calipers could cause that.
that should work as a bribe!Bed Bath and Beyond
It does not make the noise at all over 30, it only occurs with the brake applied while slowing.Jbenrod wrote:Does the noise seem to come and go as you make gentle "S" type turns at around 35 -40 mph ?
That one is more tough, I have the jack stands but won't have another willing party this weekend. I hadn't really considered something related to springs or struts, each were replaced about 60K ago. I have bounced and pulled on the springs to feel for movement, but nothing seemed amiss. Are you suggesting a possible loose or maybe micro-cracked coil spring?Jbenrod wrote:Another, BUT ONLY if you are comfortable with doing it safely ! One can jack up the front end. With wheels off of the ground grasp a spring coil above the wheel while someone else puts the car in gear so that tires are slowly spinning. Any vibration felt in spring on either side ?
I think so.If lugs are hotter than the rotor wouldn't that be another indicator of bearing wear?
