squealing noise from alternator
2004 Mercury sable SHO vulcan, 90,000 miles
Several months ago, I noticed there was a chirping noise
under the hood which happened from time to time. More recently
when I drove it in a huge rain, this noise became extremely louder.
I checked it afterwards and found the noise came from the alternator.
I guess one of the two bearings that hold the shaft during spinning
may run out of lubricant. I want to put some lubrication grease
on the bearing so that it will last longer and become quieter.
However I found it is very difficult to take the alternator apart.
Firstly I tried to take off the big bolt that holds the pulley. But it
is so... tight and doesn't work. Then I unscrewed the two small bolts.
But I still cannot take apart the back half to reach the bearing inside.
Do I need some tool to force it apart and what kind of damage may be
incurred if I do it wrong? Really don't want to spend another $150
to get a new alternator just due to the noise.
Thanks in advance
