Question about Cars & Trucks

1 Answer

I have a 2002 trailblazer-when driving my truck makes a loud humming noise and slight vibration and when I come to a stop its quiet. Same noise when I turn-I think my tires are unbalanced could that cause the humming and vibration. The humming is coming from the front end. My wheel bearings and cv joints are fine also. Please help!!!

Try jacking the vehicle up and testing. If noise still present then possible wheel bearing failure.

    The humming noise also starts @ about 20 mph

    typical of wheel bearing failure or uneven tyre tread. Try as suggested above, and if noise or vibration still present, then replace wheel bearings.

    I jacked it up and there was no play-I took the rims off and put the original tires on and it makes the same noise

    No play doesn't mean the wheel bearing hasn't begun to fail. I've had the same issue with a number of vehicles, and the wheel bearing has always been the cause to far. If the original tyres make no difference, then you are either looking at a wheel bearing issue or a front diff issue.

    Most likely a wheel bearing issue though.

  • Dustin Cosby Nov 04, 2012

    Do u think it could it be a differential bearing or just the wheel bearing-I really don't want to spend $100 after buying it 2 days ago )-:?

  • Dustin Cosby Nov 04, 2012

    or if i grease them both

  • Dustin Cosby Nov 04, 2012

    well it was the wheel bearings! thx man

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.

SOURCE: My car is making a loud noise from the front end

Hi Becky Your mechanic should be able to find your problem. They will lift your car so your front wheels swing free and shake your front wheels around. The bad part can be found this way. Theres a lot of things this could be. But yes it would be a joint or bearing. Hope this helps you.

Whining humming noise under hood


If the engine is not reaching optimum operating temperature it will indeed give you a "check engine light",the code will lean you in that direction as well.The noise your hearing more than likely is coming from the "clutch fan",they are very common on the TrailBlazers to make noise and fail.The oil light... you certainly need to have the oil pressure checked with a mechanical gage.

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.

2002 trailblazer making loud humming noise when driving


When you turn right - you're taking weight off the right wheel.
If the noise dissipates - the passenger side wheel bearing is most likely to blame.

2004 Chrysler Crossfire 25,000 mls auto, road hum noise


MOST of the hums after a while come from the diff as the back axle does the driving and almost all its life runs the same way except when going in reverse ,is the rear diff meshing and worn on both the crownwheel and the pinion and the humming gets slightly louder the faster you go and almost goes when almost stopped and this can also be the slight vibration you get so get the diff oil drained and refilled and check if there is any metal in the oil when drained if so thats your problem But it will last for years like that..Let me know how you get on RON
