What is humming noise from front end of mondeo at low speed

SOURCE: Humming noise in front end of truck

I'm having the same problem with my 2006 Chevy 2500 duramax...The humming starts at 25mph and then gets less prominent and then at 50mph it gets more prominent and louder, then at 60mph you can hardly hear it.....I did notice a little bit of leakage where the front axel meets the from diff on the drivers side.
Any suggestions?

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.....

Keep an eye on your temperature gauge until we figure this out, just in case & see if it climbs much/any at highway speeds.

Could be the lower control are bushing, it apparently is an issue with that model year.  Big bucks (850 CDN$) to fix as the 'whole' front end needs to be partially dropped and both should be done at the same time.  A mechanic should be able to see if that is a problem while the car is on the hoist.  The mechanic should be able to point to the area or point where the contact is being made. Mine lasted till 100,000 km, I heard it on the second hand test drive ( at 90,00 km) and asked a buddy ( a Toyota Master Mechanic) about it and he made me aware of it; i bought the car anyways.

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.
