My 04 ford explorer is making a loud humming noise when driving. The noise is coming from front and gets louder the faster you drive.

Does it get louder as you go faster? This could be a bad wheel bearing. Go for a drive on a safe street or road with no traffic. Drive at 40 mph and now put the vehicle in neutral and shut the engine off. If you still have this noise it is probably a wheel bearing. Try to determine which corner the noise is loudest to find which wheel bearing is making the most noise. You may need to lift all 4 wheels off the ground and test to find the noise. Be careful and use jack stands. I hope this helps. Rod

You have a defective wheel bearing most likely, the noise sounds correct for that problem. have a shop drive it before you replace anything to confirm my guess.

There is no way to estimate cost until you know the exact case of the noise. See the dealer for a test drive so a tech can listen to it.

you have a bad wheel bearing.

If the noise is only when the vehicle is moving it sounds lek you have a bad wheel bearing. You can inspect ford move ment or play shaking the tires up and down and left to right while lifted up on hoist or jack. If there is no movement doesn't necesarily mean the bearings are okay, however if there is movement in bearing replace and drive again. Antoher way to determine Which wheel bearing is bad is to drive and turn to the left, if the noise gets louder than it mens the rightside wheel bearung is bad. If you turn to the right and noise gets louder replace driver side front wheel bearing. Also Rub your hands across your tires, does it feel wavy or uneven, you could have cupped tires, I DON'T KNOW HOW NEW THEY are but cupped tires will also make this noise. One way to see if it is the tires is to do a rotate If noise changes at all then you no its a tire causing noise. Hope this helps.

sounds like a wheel bearing they start to scrape and bind making loud noise while driving only. no noise while in park

What kind of noise? Humming? Screeching? Can you tell if it's coming from front? Left? Right? Does it get louder the faster it goes? Higher pitch?

guess i should make this so you can rate the solution ... thanks

Most likely it's a wheel bearing going out.., If you turn to the right, or the left when driving the noise will change pitch. Been there done that.....
