Need help identifying cause of high RPM squeal
When winding through the gears above 4500 RPM's, I have a squealing noise that I am trying to eliminate. At the end of last year, my power steering pump started leaking and I assumed that it was the cause. However, I have replaced the pump and I still have the squeal.
My belts seem to be tight and my alternator and water pump were both replaced two years ago. At that time, there was no noise. I noticed the squeal for the first time last year.
I don't get the noise when it's not under load ( revving in the driveway). It only seems to happen as I wind through first and second gear when I get to 4500 - 5000 RPM's. Since it only happens when I am driving, I am wondering if it could be something else other than a belt or a bearing on the alternator, water pump or power steering pump. I may take the belt off of the power steering to see if that eliminates it. My alternator belt runs the water pump so that is harder to test. I have also tried spaying some WD-40 on the alternator pulley, but that didn't help.
