Have you tried replacing the tensener pulling, it has a bearing inside it that should allow the roller to spin. They are not very expensive.
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.
the bearings are probally giving out.
What kind of whining? Could be your serpentine, could be your steering pump.
it is the idler pully. i just replaced mine and all the whining stopped
