Does the sound change with the throttle? Is it speed related? Does it do it at idle?

I once had a a mechanic that would tell me to turn up the radio a bit if a complained to him about an odd noise.

Maybe you have Glenn Gould's ghost in your bus.

Hummmmmm. . .

Lin,
That mechanic must have trained several of my drivers as well!
I often find the stereo BLASTING in the buses and when I run it out to fuel it or whatever and notice a strange new noise I get "What noise? I didn't hear noth'n!"
(of course not ya moron you couldn't hear ya self think as loud as the stereo was!)
But on the other hand Blaupunkt makes one hell of a bus sound system!

There is nothing needs fixing on my bus, ever, but they hear me coming!!

Have you invited someone to drive while you search, or vice versa? Most noises I have looked for cannot be found, after I stop.

I am usually alone when I hear them, but doing walkabouts for noises at 45 MPH, I hear that is not safe.

The last hummer I detected was associated with power steering. Full reservoir, but still made noise. That one comes and goes - I will find it someday.

ck gasket around spare tire door.....some times air relays make a sound simular to humming when not operating properly but should not be constant...Is it under co piolt seat?

Busted Knuckle · March 04, 2010, 05:19:29 AM

What kinda tune is it? Rock, country, hip-hop, blues, gospel, etc?

Seriously, if we knew the tone or tune it makes it might be easier to hunt down.
