i need help diagnosing this noise, it sounds like a helcoptor rotor or some have said a train haha i thought it was a warped drive axel but i have changed both and no changes some say it sounds like a bald tire so i changed all of them still no change i have ripped apart my front end and put it together coutless times the only thing left i can think it is, is a worn diffrential so i purchased a tranny but it needs all new bearings go figuree,or a wheel bearing, its a 95 civic by the way, if anyone responds ill put up an audio cli[ of the noise,also when turning left on a freeway ramp it stops. to anyone that helps thank you in advance

 

Do you notice anything unusual lifting the wheels off the ground and turning by hand? It should be completely silent when you do that. Also there should be no play or wobble when you pull on the tire (top to bottom and side to side). Check all 4 wheels one at a time.

Turning left shifts the weight of the car onto the right side wheels, so that suggests the problem is on the left side typically a wheel bearing.

 

all of the wheels are fine but when i have it lifted and the tires off it doesnt make the noise

 

It's not going to make the same noise. If you hear ANY noise turning a wheel without the weight of the car on it, it will get a lot worse with the weight of the car on it.

 

no noise when turning the wheels just when its in motion,do you think its the diffrential?

 

i just checked the driver side front wheels has a bit of play
