Ok, this is a wild one...
Clutch slave cylinder gave out on my 315k mile Ranger. Two teens learned stick on it, but they didn't wear out the disc!
Anyway, spent most of my Christmas break sliding under that thing replacing the clutch. Kept the old flywheel, but put in a Sachs kit with new pressure plate, clutch plate and slave. Replaced the pilot bearing, which was destroyed, nothing but the outer race left! Got it all bled and took it for a test ride.
Every time I got on the gas, it made a whirring sound, kind of sounded like metal sliding along metal. I noticed it in the lower gears, not so much in the higher gears. Sound would go away when you let off the gas or pushed in the clutch. Wouldn't do it in neutral.
Here's the clue: it would sometimes happen as you went over bumps, and it would happen as you started the engine.
