SOURCE: There is a loud noise at 45mph.

Find a quiet empty stretch of road. Go 50 mph, put the trans in NEUTRAL and shut the engine. If noise is still there, swing car left and right to detect noise differences. Could be hub or axle bearings. Not engine or trans if noise is still there. Hope this helps

Have a mechanic check lower control arm bushing at the rear of the control arm.It is a horizontal bushing retained by a vertical bolt clamping it to frame.The tire will move more forward and back more than it should during braking. canuck mechanic.

I have a 2005 chevy cobalt that is making a humming noise after 20 mph. I can also feel a vibration in the gas petal. "noise" increases with speed. Higher milage and just had struts replaced about 150


squeakey69 is right it sounds like you have a wheel bearing problem cobalts are notorious for wheel bearings going bad i would go ahead and change both front bearings because if one is going bad the other usually isnt far behind hope this helps.

Front end hum/noise


The hum could be being generated by the tires. I would move the rear tires to the front (as they are a different brand) and see if the hum is exactly the same at the same speed.

High speed hum can also be generated from the design of some types of brake rotors but I doubt that is the issue in this case.

From what you have described I would not have thought the problem would be wheel bearings so I am surprised that was the diagnosis before a more careful investigation was carried out. I would have tested the tires first. (I would not have put the old wheel bearings back in either after they had been changed).

Doesn't matter what stabilizer does--- the bushings need

Maybe you replaced the wrong drive axle

Put the front tires on the back to see what happens

No real problems, just shopping for the best tires for Wisconsin winters. This is my second Chevy Lumina, the first was a 96, which was hit by a drunk driver while parked, and destroyed...nobody...


Make sure you get snow tires not all seasons. Get a tire with a "Mud and Snow" tread design. It may also be called M&S. If you experience a lot of icy conditions, give serious thought to getting them studded. Todays new tread designs give you the traction you will need to wade through snow but not the road noise that there used to be. Look for deep lugs with wide gaps between them to move snow out of the tire track. That way you will be the guy driving home while the other guy's are waiting to get towed out. Hope this helps.

Alot of vibration and shaking when driving the vehicle.


there is a few things you can troubleshoot to find the problem. First I would check your front wheel bearings,when these go bad there is a slight hum, but if left to worsen you could get a loud hum/shaking/vibrating like the car is posessed! Second I would check your inner and outer tie rods for play. and,Third I would check your front tires, if there is a bump on your tire or if the inside of your tire is worn due to bad alignment being a front wheel drive car you could experience the same symptoms. I hope you find your problem and god bless.

I have a 2005 cobalt and it has a humming noise in the rear of the car. can't pin point where its coming from?


Does it hum sitting as well as driving?Your fuel pump could be the problem some will make a noise before going bad.It sounds like something turn on,and shouldn't be!

1999 Subaru Legacy GT - Front end humming


@ 175K miles the Idea of Transaxel Output Carrier Bearings Should Be Considered. BUT What you Describe My Experience tells Me Wheel Bearing, It Being a All Wheel Drive Vehicle Makes it Very Difficult to Call This with Confidence as I Am unable to Roadtest it. Hope this Can Help To Lead you in the Right Direction
