I just got my 85 QV. Drove it 590 miles from down south to my house with no problems. Put it to bed. I got up started it the next morning and now I have this squeal. I do not think it is the throwout bearing as the noise changes with the engine speed and not by depressing the clutch. The clutch engages fine with no binding in any gears.. It is definitely not any of the belts, or alt or cam bearings. It is definitely coming from the location of the lower transfer gear area. I think it may be low on on gear oil. I want to check, possibly add. Does any one know the hex size for the top of the transfer gear assembly to add fluid? Also, has anyone experienced this problem before?
