Oh, it is called a 60 cycle hum, i doubt anything is wrong with it.
Not much info to go on but, it could be a wheel bearing going bad.
If a car has a loud humming noise when accelerating, it could be that the air filter is missing. The air filter housing might also be loose. A loud humming noise can also be a signal that there is something wrong with the alternator belt or the fan belt.
We cannot and do not diagnose your computer problems remotely. Take it to an engineer.
Is the humming noise happening all the time the brakes are applied? Does it change pitch as the car slows? Is it loudest just before stopping?
as far as the humming noise and the grinding noise it sounds like your power steering pump is either out of fluid or gone bad completely. as for the muffler? ?MAYBE? the strain from the bad power steering pump is overworking the engine causing it to make noise? answer definetly a bad steering pump as for muffler, the sound can be transfred and magnified on a car, replace steering pump before bothering about the muffler sound may be gone
need to get your wheel bearings checked
either your hand brake has got something wrong with it and is stickingm, so that makes your tires rub against the road which makes a horrible noise!
Depends on where the noise is whats making the noise. Can you be more descriptive of where and what?
Maybe Eh-Uh! ?
Possible bad left front wheel bearing. ditto the wheel bearings, get them checked both sides front and rear. This is a serious safety issue.
Compressor locked up.
The problem is Owning a 97 Breeze.
