Have a '48 2-ton with a 1954 powerglide 235 engine in it. Truck came with the NO free play in the clutch pedal and lots of squalling noises coming from the bottom end with the engine running and the clutch depressed. Throwout bearing right? Wrong. We replaced it this afternoon, inspected the clutch, greased the release arm pivot point, adjusted the clutch and voila! Same noise. :mad: :mad:
Sounds like something rubbing on sheet metal, very similar to a problem on another vehicle a couple of years ago when the outer ring of the harmonic balancer slid back into the timing cover.
Noise only appears with engine running and the clutch depressed. Let it up and it goes away.
We're looking for ideas on what to check next, any help, ideas or wild guesses appreciated.
