Hello,
My 95 (4.0 5sp) has started to make a wistling whiny noise that is RPM-dependent. It starts as a soft wistle and will go away all of the sudden. I have not been able to point out what's causing it, but seems to come from the A/C pump, alternator or water pump area. The A/C pump is not turning, and turning the A/C on makes no difference. I'm starting to think a bearing in the alternator may be going bad, or maybe in the water pump. But why would the noise go away so suddenly? What could be causing this?
Thanks,
Mikel
