Worn bearing and new belt is tighter than worn one?
Alternator is defective and needs replacing.
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.
Check the belt tension. it is too hard on the bearing or it's running dry.
It is the alternator....
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.
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.
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 .
