My car been running really noisy recently the sound seem to be from the engine bay A vibration or a humming noise at low speeds then turns to a high pitch noise while in high speed 60+ my mechanic told me the Wheel Bearing is good he said it could be an possible bad Flywheel shifting into gears seem to be fine what do u guys think the problem is your info is greatly appreciate !!!!

95 Maxima GXE 5 Speed 137K

 

Maybe it's a belt or pulley

 

Thanks anything else u guys could think of ???

 

does it make that noise when it just sits in one spot?

 

Does the sound of the noise change based vehicle speed or engine speed? How about while shifting?

 

mostly only when the car is moving very quite when it's in one spot while i'm on neutral it's quite even when i step on the gas on neutral it doesn't have that noise only when the car is moving

 

Help Please !!!!!!!!!!!!!!
