Hi smart mechanics, ever since I bought my 2002 Ford Explorer XLT 4x4, I have heard a decently loud humming from the back. Then, this morning, I heard a deeper hum as if it was coming from the front (it was on the highway 60-65). If you could answer that, that'd be great. Also, I have another problem; it seems that when I turn right, I feel grinding in the left tire (or so I think) could this be the bearings? If so, please give me a rough estimate of how much all the repairs would be. Thanks for putting your time into my questions.
When you turn and hear a noise it is usually a CV Joint that is going bad. Humming can be a lot of things. Tires wheel bearings, rear end differential etc.

Replace "idle speed motor" (also known as idle air contrl valve).
SOURCE: My front end makes a loud humming noise.
Alignment will not create a sound by it's self. The most common cause of humming (especially if you have an agressive tread design)is a wear pattern in the tires...check for that or rotate the tires around & see if the noise changes. If it does then you know it's in the tires. & Not always, but most of the time a bearing noise will increase or decrease in intensity if you load up one side at a time by doing 35-50 mph & turning slightly to each side.

make sure your tire is ok and is not r ubbing on anything and check your drivetrain ujoint`s etc.
Testimonial: "Well ill what I can do and thanks for the advice"
SOURCE: sound at the front left side starts at 30 miles
jack up the front end and grab the tires at the 12 and 6 o'clock positions and shake them. if there is any play your wheel bearings are bad.
