Worn bearing and new belt is tighter than worn one?
It is the alternator....
Your child in the backseat.
Alternator is defective and needs replacing.
I replaced the engine idler pulley that I bought from Autozone for about $17 and eliminated the noise. I initially thought the bearings on my alternator were going out but when I replaced the pulley all the whining noise disappeared. Good Luck!
1. Suspect the belt is loose. Tighten it or use belt dressing. 2. Bearings are worn out on the alternator. Replace the alternator. 3. Poor workmanship on a rebuilt alternator. Replace the alternator.
One source of whining could be many things but the first that comes to my mind is the Alternator. The CV joints could possibly make this noise too but I would personally consult a mechanic about this. any motor attached to the engine could be a cause but I would take it to a mechanic: alternator, compressor, water pump, etc.
It is probably the alternator that is whining - and not charging so you have run out of battery power and it won't turn over.
How do you replace an alternator on 2008 dodge Avenger? My car is making a whining noise and this may be the problem.
it is the idler pully. i just replaced mine and all the whining stopped
What kind of whining? Could be your serpentine, could be your steering pump.
the bearings are probally giving out.
Probably a loose belt. If it makes the sound while turning it is the power steering belt. If it is constant until the engine heats up it is either a serpentine belt or alternator belt.
I would say probably not, the reason your battery is weak is I reckon due to a fault with your alternator. It is obviously not producing sufficient power (electricity ) to keep the battery charged. The whining noise is probably caused by worn-out bearings. A replacement or re-conditioned alternator should cure the problem .
I also heard a whining noise on my 2003 Cavalier. It turned out that the plastic covers on the nuts that hold the hubcaps on had cracked after I had my tires rotated. It seems silly, but the whining stopped after the covers were replaced. My check engine light comes on after I pump gas at a different gas station than the one I usually go to, regardless of speed. It goes away after I drive for a few miles. That may not be the case for you, but it's worth noting.
If it makes a loud whining, screaming, or grinding noise, it needs to be replaced. Before you do, verify that it is indeed your alternator and not a pulley or other engine component If you suspect low output is why it's bad, the only way to verify that your alternator is bad is to attach a diagnostics tool, or remove it and take it to a local automotive parts store. Most will bench test your alternator for free.
Whining noises often come from the alternator or the steering pump. Check the power steering fluid in the pump (there is a dipstick on the pump), and have an AVR test done on the alternator. If the alternator is faulty, you are probably having battery problems as well. If the steering pump is low on fluid or is faulty, you probably are experiencing jerky steering from time to time.
sounds like the alternator belt is loose, check it out and let me know.
the Idle Air Control (IAC) is bad and needs cleaning or replaced
The whining could be related to the alternator. Does the car have any electrical problems such as the battery drains and dies while car running, are your belt(s) tight? in good condition? It might be a belt tensioner or idler pulley that is causing the whining.
could be the fuel pump...or the alternator...:)
Faulty wheel bearings usually squeak or squeal. A whining noise is more likely to come from a power steering pump low on fluid, or from a faulty alternator.
I would check your power steering fuild.
It could be your serpentine belt slipping, you should have the car checked out before it gets more serious.
