The problem is in the tire balance.Go to your local tire shop and have the tires rebalanced.
answer more that likely is not tire balance tire balance will feel ruff at certain sppeds humming is either tire tread noise on pavement or wind noise but most likely to be tire tread only way to fix is to buy different tires or dont drive at 70 mph,lol
AnswerI don't think it's the tire balance. Humming at higher speeds sounds like a wheel bearing to me. If the sound is less when you're turning one direction, then the opposite wheel bearing is the problem. It's a cheap part and a quick fix; more painless than new tires, which always need to be replaced in pairs at least. Tire problems are way more commonly felt in the steering and suspension, and not really heard.Possible wheel bearing going bad.
wheel bearing
Unplug it.
The differintial is starting to wear...
check your wheel bearing
sort of like a humming? wheel bearings dude! if it starts humming at about 30mph and just gets louder faster you go, its the wheel bearings. and get used to it, i have blown 4 on my ion 3
Most likely the humming noise is coming from a contactor located in the outdoor unit if you hear the noise outside or from the air handler or furnance located inside the home,if the hum is inside the home
possibly your running RCAs on the same side as your power cable
Could be a bearing going bad.
its probably your radiator
when the pump is going out it will make a humming noise from the bearings even if the resivore is full.
Could be many things but a front wheel bearing/hub assembly going bad comes to mind. Scalloped worn tires can give you a humming noise also.
