My 2001 chevy blazer makes humming noise when i drive. i just put new tires on the front and the had alignment fixed. noise is progessively getting worse.

the noise is coming from the wheel section, it's called air splash, humming varies with speed, main causes are wheel alignment due to loose ball joint, check if your tire erodes on one side, next check your disc brake for clogged air cooled vain and disc wearing

sounds like a right front wheel bearing. when you turn to the left it puts more load on the right bearing. when you turn to the right it puts more load on the left bearing. These are a bolt in style bearing and they are fairly easy to replace.

If you think you would like to give it a try let me know and I'll get you some instructions.

does it get louder above 45-60mph? and much quieter at low speeds. It could be wheel bearings, a rear differential or front differential. If its a grinding humming noise its wheel bearings, listenin to see if theyre coming from the front or rear, left or right, or both when your driving to know what wheel bearing are bad. If its a whinning noise, its probably a differential. check and listen to hear if its coming from the front or rear. Also, check for loose plastic around the wheels. Lastly check your tires for uneven or choppy wear. move your hands front to back on the top of the tire. does it feel really choppy and rough, maybe you just need new tires

Could be road noise from a shifted belt in the tire. could be a drive axle going out. those wheel bearings dont hum 99% of the time when they go bad,generally they have a low grinding sound,espesially when you turn,and your teering gets a bit loose and sloppy.
also check to make sure that you dont have a broken strut that may be touching the tire..try putting on your spare and see if that fixex it,if so its a shifted belt in that tire.

Try moving the tire to a different position and see if the sound stays with the tire or stays in the right front. Does it do it when braking, accelerating, driving straight all the time? Also - if you get on a long straight stretch of road with no traffic - switch it to neutral and turn the engine off - REMEMBER - you will lose power steering and brakes with the engine off.

They now have a bearing assembly, you replace the unit as one. The humming sounds like a Blazer I did last week. Same noise/humming over 25MPH..? Sounds just like road/tire noise. Hope this helps.

WI replace the wheel bearing and put brakepads on.This is when the problem start...When I am driving I hear a stumping and humming sound. 1996 CHEVELETE BLAZER . YOU CAN PUT IT IN FOUR WHEEL DRIVE

check to see if front tires are cuping or feathering on outside of tread if 4wheel dr some alinement shop set toe &cam to pull center causeing this witch when tire wares makes this kind of noise.

It sounds like a possible bad front wheel bearing they will make like a humming or growling noise.The pull could be air pressure a little lower in the right front tire than the left front check the air in all tires and if pull is still there take the left front put it on the right front and put the right front tire on the left front.Sometimes tires get what they call radial pull and that will fix it or make it go the other way if it goes the other way either get new tires or put the back tires on the front of the vehicle and put the front tires on the back.

it started with a low humming noise and got worse it probably our wheel bearing good luck pierre
