Hi all,
I've recently bought a 2003 Explorer XLT, 4x2, 4.0l . It's my first SUV and I am very happy with it.
Just this one thing though: from time to time I notice an annoying noise coming from the rear side of the truck. I wouldn't call it a howl, it's not loud enough, but more of a persistent wooooooooh sound, like something is rotating. The pitch seems to be related to my speed.
It is most noticeable above 35mph. I initially thought some kind of air resonance is taking place, but the sound disappears immediately when I take my foot off the gas pedal. It is most annoying when I am driving on smooth pavement or the highway and need to slightly hold down the gas pedal to maintain speed.
It's not very loud, but loud and consistent enough to be noticed and spoil what would otherwise be a very smooth, quiet ride.
Before I take it my explorer to the dealership and embarass myself making that woooooohh sound to them, does anybody have any idea what may be causing this? Is it something that can be expected or something I need to have checked?
Regards,
Johan.
