I have 2003 Kia Spectra 5 speed w/11kK miles. I am getting a high pitched whine that becomes noticeable at around 35mph and get louder as speed increases. I can push in the clutch at highway speeds and the whine goes away.
High pitched whine when driving. on 2003 Kia Spectra
Sounds like a worn out throwout bearing. The transmission will have to come out.
