Sorry James, I didn't mean for it to sound like *you* were trying to avoid
troubleshooting. It was more an observation/statement about the result of
improper (or lack of) troubleshooting...whether intentional or not. Any
time one replaces parts that did not solve the problem, one did not perform
the *proper* troubleshooting. To your credit, you tried harder than most.
I wish I had a dime for every water pump, alternator or p/s pump that's been
replaced because of a squeal in that area, only to find out it was the belt
at fault. While I can't say that is your problem, it is more common than
you might imagine.
A sure way to tell if the noise is from the accessories or something
internal is to remove the belt. Still have the noise...internal.
If one of the accessories was causing your engine to stall, you would not
likely be able to turn the pulley by hand. While some naturally turn more
freely than others, you should still be able to tell if there's any binding,
wobbling or roughness. They should each turn smoothly. Don't forget the
idler and tensioner pullies. If all those check out, it's likely the belt.
If the sound is only heard when the AC compressor cycles....well...that
should be obvious.
Generally, if you have a damaged bearing the clearances will be greater than
normal resulting in lower or no oil pressure, depending upon the severity.
And it will get worse.
HTH.
