I have a 91 240 that has been M46 swapped that has developed a high pitch squeal/whistle that seems to start around 60mph. It is speed dependent, not engine RPM dependent. It's varies in loudness and sometimes seems to almost disappear. Because of its high pitch nature its pretty hard to pinpoint a location but I feel like its coming from the front of the car, but don't hold me to that. It will happen in both 4th gear and overdrive.
I originally thought it was a wind noise, but I'm increasing thinking something mechanical.
My thoughts are wheel bearings or maybe the driveshaft bearing.
Is there anything else I should look out for? I appreciate any ideas.
