98 chevy cavalier (humming sound)

Have you checked the CV Axles? Since the noise goes away turning left to right. Another slim possibility may be the brake calipers but you said humming. And I would (assume- which means not always so) stuck calipers would only make the noise in one direction.

Most likely a wheel bearing good possibility it is the right one if it gets a little worse when you turn to the right then its probably the right side wheel bearing, they tend to get louder under load. Also slight chance it could be a bad tire.Howie

If the sound follows vehicle speed and not the engine you could be hearing u joint noise from the Driveline also. Will get progressively louder with speed.

the humming sounds like a wheel bearing problem cavaliers are notorious for the bearings going out i have changed many of them, i would change both front wheel bearings at the same time and not just one it will save you in the long run. hope this helped

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.

could be wheel bearing ,left side

you have a wheel bearing going out. see if it gets quieter if you turn one way or the other that will tell you what side it is on

usually if noise is made when turning right it would be the right wheel bearing easiest way to check would be to lift the car off the ground on that side until tire clears the ground and spin the wheel to see if it makes noise also try grabbing the wheel on the top and bottom at the same time and see if you can move the wheel back and forth checking for slack.

that would most likely be tires and/or wheel bearing, common thing on these cars, also a way to check if its wheel bearings is to listen when you turn, does it get louder when you turn left or right, if it does it sounds like wheel bearings, run your hand on the tread of the front tires, are they smooth or does it feel jagged? if it feels jagged then you need an alignment. i'd have a shop check the wheel bearings and alignment.

That's indicative of a wheel bearing, which is why you were told to change that out. However, it's also possible that the carrier bearings in the differential (where the drive axles attach) have gone bad. That happened to me on my 300ZX several years ago, and I had to replace the diff bearings. I would have them checked out somewhere other than a dealer (you'll probably get a better price from an independent shop).

As a sidenote, to be sure it wasn't a wheel bearing, if you hear it quiet down in a turn one way but get louder in a turn the opposite way, it's likely the wheel bearing. If you turn left at speed and it gets louder, then it's the right bearing (since you're loading up that side of the car). If it gets quieter in a right turn, it's the right side (you're unloading that side of the car and not putting as much weight on it, so it doesn't drag as badly). See if you get that symptom just to be sure that the wrong side front wheel bearing wasn't changed.
