Hey everyone,
I purchases a 1987 F250 that a PO has replaced the 6.9 with a 7.3 (unknown year). I get some pretty nasty noise (gravel in a coffee can) in all gears (ZF5), and to a lesser extent, sometimes in neutral with the clutch engaged, but not always. Press in the clutch and the noise goes away for the most part. My first inclination was input shaft bearings in the transmisison, but as i do some research of my own i am starting to lean towards a failing dual mass flywheel and/or pilot bearing. For those who have had flywheel issues, do my symptoms point to flywheel problems, or would you guess transmission problems? There is also a very brief but pronounced rattle at engine shutdown.. im not sure if this is inherent or another sign pointing to the flywheel? I realize that the ZF5 is a noisy transmisison, i am not concerned with the whine at all, just the nasty noise.
Kind Regards,
Alex
