A bad pinion bearing in the differential is to blame
It is the alternator....
if it sounds like a high pitched whining then it may just be your cool air intake
Friction in the transmission system may cause whining noise when a car is accelerating. A poor engine or clutch assembly may cause the excess friction in the transmission system.
it is the idler pully. i just replaced mine and all the whining stopped
The whining noise is a common sound and problem with all Chevy trucks and suvs. Yes it is the fuel pump and it does not mean the pump is going out. Chevy recommends to keep the fuel tank 1/2 full at all times to keep the electric fuel pump cool. I've installed many NEW fuel pumps and they also whine/ make noise. It is just a common problem. If you are concerned about the fuel pump then you need to check the fuel pressure with a fuel gauge.
Well without further analysis or information, a short answer would be that your engine is BROKEN.
ON the 2006 impala that whining noise is actually the electronics when you accelerate. Its more or less electronic pulses/signals My 06 Impala is the same.
when warmed up high pitch noise at idle and it gets louder during acceleration Response to : Can someone actually answer this question? This is my question and the above answer makes no sense.
when you try to start it then it's the starter.
What kind of howling? Or is it a whining? Where does it sound like it's coming from.
also, check your power steering fluid levels. The noise you hear is the fuel pump.
When it starts leaking are making noise.
