Because the whine is still happening at high speed when your in neutral and low rpms it should not be engine or tranny related. I would start looking at wheel related issues. Hubs probably.

Noises are very hard to diagnose without hearing them. Typically, if it was a belt, the pitch would change with RPM of the engine. Whining noises can sometimes be attributed to an idler pulley, alternator, power steering or waterpump bearing going south.

I have a humming noise in my 2003 ss Chevy Silverado. It's loud in the cab but you can't hear it outside. The hum sounds like underneath somewhere. I heard it might be a belt or the tires. thank...


If it were the belt you would hear it clearly with the hood open! So if you don't it probably isn't the belt - but you should still check the condition of the belt - any cracks?
The tires would be loudest if the windows were down and driving - if that isn't the case - probably not that either.

Humming noise could be many things and you need to localize the problem. If it sounds like an electronic hum you might want to check the fuel pump since you almost sit on the tanks.

Try turning everything off - radio, ac, etc off and see if you can at least localize the sound to a particular area.

My 2006 X-Terra just started to make a mild screeching noise once I begin to drive it right after the initial start-up. The noise does not appear again until I let it sit for a bit (like overnight or...


It sounds like a belt may be beginning to slip. Open the hood, take a flashlight and check all of your belts for glazing on the inside of the belt. Also check for fraying on the outside of the belt. Try to remember when you last changed your belt.

Also, after your car sat awhile, open the hood and have someone else start it while you look under the hood for a slipping belt. It helps if you have marked the belt with a red permanent market so you can see the movement of your belt.

In time, if you do nothing the screeching will get worse and start to happen more often to all the time. It may take a while before your belt finally breaks.

If it is a water pump belt, it will affect your cooling system and if it is an ac belt it will affect your ac system.

probably the belt making noise , very common .

WHen a belt gets old it gets dry and cracks start to appear , the non-ribbed side of the belt may get dry & glazed also make noise . common problema are also tensioners that make the belt get out of line with the rest of the pulleys , look carefully because just a little miss-alignment can cause a belt to slip on the smooth side of pulleys and make noise . Misting water onto the belt may also help you determine what is making noise.

Good Luck and Watch your Fingers !!!!
