there can be a crack on exhaust manifold or on eghaust muffler.

Try jacking the vehicle up and testing. If noise still present then possible wheel bearing failure.

there are actuators in the transmission that control pressure and shifting

sounds like a wheel bearing in your right front. apparently, there are different types of bearing setups for this vehicle, depending on wheter it's 2 or 4 wheel drive. when you are turning, you unload the faulty bearing partially, and the noise quiets down. bet it gets noisier when you turn the other way. the noise probably also changes pitch with vehicle speed. get it checked, as this can cause more serious damage, and left alone for too long can allow the wheel to come off completely!

Hello! If the humming noise is speed related(gets louder as vehicle speed increases)check front wheel bearings. If the noise goes away when turning one way or the other then it will most likely be in the front wheel bearing. If you turn the wheel(while moving)to the right and the noise goes away it is on the right side. If you turn the wheel to the left and the noise goes away its on the left side. Hope this information helps!

sounds like a wheel bearing assembly,if the noise changes when the wheel is turned a little bit while driving then it is a bearing,hope this sheds a little light on it for you

It sounds to me like the explorer has a bad hub bearing up front.I would have this checked out especially if one has become loose.The hub bearing take the place of what use to be wheel bearings:)

SOUNDS LIKE YOU HAVE BAD LF WHEEL BEARING..JACK UP FRONT OF VEHICLE..BLOCK REAR WHEELS..PUT TRANSFER CASE IN NEUTRAL,SPIN EACH FRONT WHEEL BY HAND WITH OTHER HAND ON COIL SPRING..YOU SHOULD FEEL ROUGHNESS IN SPRING ON SIDE THAT HAS BAD BEARING..IT IS A HUB/BEARING ASSEMBLY

It sounds like a wheel bearing. Depending on the miles it is possible it could be under warranty.
