Noise from behind Fly Wheel

F350 Fly Wheel Noise - YouTubeHave a loud noise coming from whatever you call the thing that the Fly Wheel bolts onto. Has a little bit of a wobble to it.

Don't know where your located, however, if you google Trucks Unlimited and call them. Ask for Scott, if he can answer your questions. He's out of Winston-Salem NC. area. Anyhow, I do know that the flywheel bolts to the crankshaft. Your clutch, pressure plate, throughout bearing all bolt to the flywheel. The pilot bushing goes into the end of the crankshaft and that's what the tip of the input shaft of the transmission goes into. It could be the tip is broken off, or just the pilot bushing is bad, or crankshaft, or flywheel bolts loose. It's something of that nature I'm sure, however, call him. He's "The Man." I wouldn't trust anyone else to do it but him.

Everything was tight. Cody at PHP in Winder GA suggested that it may be a cracked flexplate. I have read up on this over the last several weeks and it seems to happen more often than you would think. I just about have transmission out, borrowed a transmission jack yesterday. Looking into flexplates that are not on the cheap end but are not has expensive has billet, still looking. Hoping the weather lets me at least get the flexplate off today so I can inspect it. Previous owner had it off before when he upgraded the torque converter and may have contributed to the issue?? Will post my findings. If I don't get it off today then it will be at least another week before I have time to work on it. Thanks guys.

Oh, well you just changed things around. The flex plate is the Auto tranny's version of a flywheel. When you said flywheel, some of us thought manual gearbox, and those flywheels' usually don't break, but they can become loose. Now that you have changed it to an automatic and a flex plate, then the broken flexplate could quite possibly be the problem.

do you hear it, only at idle? Then goes away with the slightest of throttle? Sounds like flexplate to me. Replaced one in my buddys' truck. Like you, didnt want to spend too much nor go cheap, so he went oem route.

Rev up past 1200 RPM and it would stop.

Learning curve.

It was the Flexplate, broke all around the outside of the center bolt pattern. Went with OEM. Got Tranny bolted back on and was just getting Transfer Case jacked up when rain hit, called it quits until next weekend. May have to get an extra set of hands.
