This sounds like (passing) resonance -- a natural phenomenon. You might be able to eliminate it by just tightening some bolts in the exhaust system -- or, it may never go away, or it may stop of its own accord.

I have a 1997 ford expedition xlt humming noise


your differential has no effect on your rpm range the diff is part of the drivetrain components im not quite sure but this might sound like a bearing starting to go out. Question is is the noise coming from the motor or the differential to figure this out drive the vehical and while it is humming shift it in to neutral if the humming noise is still present then it would be part of the drivetrain. if the noise goes away then you know its the motor making the noise.

Won't turn over... just makes a clicking sound... and a wierd humming sound.


Try cleaning your terminals at the battery, even if not corroded. In my years as an alarm/radio installer I have come across this problem constantly, especially on GM vehicles.

I have a stock '02 RSX-S with 93K miles.I recently started hearing a ticking sound coming from the engine while accelerating at low rpm's in any gear (i can hear it at higher rpm's too, but at that point...


Sounds like an Exhaust Manifold leak on only one cylinder. The Gasket is probably blown out. Check around where manifold is bolted to the engine. Any leaks are usually evident by a black sooty deposit.

2008 dodge caravan 31k miles. I devevelped a drining hum.


Since you are still under warranty, I suggest getting your transmission checked at a dealer. We had to get ours replaced at about 28M miles. It was making wierd noises, especially in a parking lot at low speeds and when turning slowly.

There is no dipstick for the transmission fluid on our model :(

If you recently changed tires, then that could possibly be the noise too.

2004 Chrysler Crossfire 25,000 mls auto, road hum noise


MOST of the hums after a while come from the diff as the back axle does the driving and almost all its life runs the same way except when going in reverse ,is the rear diff meshing and worn on both the crownwheel and the pinion and the humming gets slightly louder the faster you go and almost goes when almost stopped and this can also be the slight vibration you get so get the diff oil drained and refilled and check if there is any metal in the oil when drained if so thats your problem But it will last for years like that..Let me know how you get on RON
