Hey all,

My '98 JGC recently started making this howling noise when I first start it up. When it first started, the noise would disappear once the engine warned up, now I hear it on & off as I drive (of course it went away when I took it to my mechanic). The noise is not terribly loud, but seems to be getting louder as time goes on.

This noise can be heard when the vehicle is parked.

Thanks
