My 2003 Odyseey has a intermittent high-frequency whin coming from the front. What is the cause?
This whin is intermittent and is not there when we have taken it to a service repairman. It is definetly located in the front of the car. It is not coming from the tires. The tires are in balance. It is not a vibration. It sounds like a natural frequency of some sort.
It could be in need of a transmission fluid change. If the filter gets clogged the front pump could cavitate, or suck air, and in doing so will make a whining noise which can sound like a whine or a whistle. It could also be something unusual -- I had a 1989 Buick Century that made a rapping/vibrating sound, I ended up finding out this came from harmonic imbalances in the power steering fluid lines that ran along the firewall -- the fix was to replace the lines. I'd look at the transmission as a possible culprit first, have the fluid changed.
Yet another possibility is a bearing in the alternator, power steering pump, etc. As the bearings go out on these accessories they can cause whining/grinding/rattling sounds, depending on how they are failing.
