Hey all,
I'm hoping someone can assist me with a recent problem. I have a 2004 Scion xB 5-spd manual with 150k miles on it. Recently I have noticed a whine when driving. Usually the whine manifests itself when I'm traveling above 60mph. I initially thought it could be a wheel bearing or possibly CV-joint; yet when I engage the clutch the sound goes away. Unable to be in the engine bay while traveling @ 60 (LOL); I rev'd the engine with the transmission in neutral but I couldn't hear anything. So if I can only hear the noise while traveling at 60 and gears engaged; could this be a clutch or transmission issue? I haven't noticed any power loss or engine stalling/vibrations (beyond that of an engine with 150k on it); so I don't think it is an engine problem.
Any ideas? This power-train is shared by the Scion xA and Toyota Echo. The box has gotten me to work for 150k so far; I'd hope for it to continue for another 50k-100k. Any help is much appreciated.
Thanks,
Daniel
