Remove the serpentine belt and check the belt and pulleys for damage. While the belt is off, turn the alternator by hand listening for the noise.

Why is your engine making a whining noise when you accelerate on a 1999 Chevy s 10 4.3 liter?
Check the fluid level in the power steering pump, it may be low. Also check for excess play in the water pump bearing, the idler pulley bearing, tensioner pulley bearing and the alternator bearings. It may also be low on transmission fluid. CHECK. If it is not low then the transmission filter may be cloged up.
How do you grease alternator bearings?
There are two bearings in an alternator. One (the large one) is a standard ball bearing arrangement. The other is pretty small and is a needle bearing type. Neither are really serviceable. You would have to disassemble the alternator to do it and by the time they need it the alternator is generally shot anyway. If you are hearing a squeal from that area it probably is not the alternator anyway. It is probably the belt tensioner next to the alternator and they cannot be repaired either.

Possibly if the bearing is bad it will freeze up and stop when the bearing gets hot from friction.

Bearing failure. Have the alternator tested. describe the whine - is it proportional to the speed? It oculd be because of the load and the charging - how is your battery condition? Did it do this before? Bearing failure. Have the alternator tested. describe the whine - is it proportional to the speed?

How do you know your alternator needs replacing?
In my case the bearing went bad and "froze" making a loud noise and making the fan belt smoke. If it does not make a noise, check the voltmeter on your dash - failure to charge could indicate the alternator is not working, but I think others things are more likely . It should be easy for a mechanic to test to see if the alternator is charging.
Does wheel bearing effect alternator?
No. Completely different systems which aren't connected to each other.
