SOURCE: 2008 siverado. Front-end humming. Sounds like

it is your wheel bearing. the bearing is a sealed unit so you replace the hub assembly. remove wheel,caliper,brake rotor.if it is 4x4 loosen axle nut. there are three 15mm bolts on back side of spindle remove these and slide hub out replace with new one. most hubs come with new wheel speed sensor so remove harness from connectors or if no new one remove the screw holding it in place to hub and slide out.

My daughters 2006 HHR LT was making a grinding / Bearing noise .I took it to a local mechanic to let him test drive it. He didnt even drive it 100 feet and imediately said "You have a wheel bearing out" He changed out the assembly for around $200 and it is good as new. Hope that helps

if the noise changes if you swerve on the road it would lead towards a wheel bearing if it stays the same rotate the tires and see if the noise changes to the rear

My town and country is making a loud humming noise


It all depends if the humming sound comes from the engine or the transmission. Check the idler bearings, the water pump bearings or the belt.
also if there is fault on the alternator or AC pulley there can be humming.
finally if the noise is heard while the car moves , then check on wheel bearings and axle ends .

Loud humming noise.starts around 25mph...can hear it all the time even at 65mph...sounds like a quiet lawnmower..


I am sure its the wheel bearing, now you have to figure out which side and that is done by loading the bearing while driving.

Have a strange humming noise that can be heard


Hi:
Often "humming" noises like what you are experiencing are caused by a failing bearing somewhere. Some usual suspects are wheel bearings, alternator bearings, and sometimes even your waterpump, but usually it starts leaking too. To start narrowing down what it is, have someone ride with you to see if the noise is coming from left side or right side, or engine area, then see if it happens when the car is not moving, or just when the drive wheels are pulling the car? This way , hopefully you can pin point the culprit!

Noise coming from the rear end of my 2004 honda pilot it really only occurs during cold weather and after it warms up you hear it slightly


When does the noise occur, while driving only, or driving and idle, in gear, or in neutral and park? If it occurs all the time (while driving and at a stand still in cold weather) it could be the fuel pump. If it occurs only while driving, it may be a wheel bearing. Describe the noise (humming, grinding, whirring, etc), and what is the mileage on the Pilot? Answer my questions so I can fine tune my answer. Thanks!
