95 powerstroke clanking knocking?

I recently purchased a 95 f250 4x4 5spd powerstroke. It has 160k miles. The truck had a lot of issues when I bought it. ,I have replaced almost everything on the front axle. And ujoints on the rear driveline. front driveline seems tight. All fluids are full and my rattle has improved it seems after topping off fluids and replacing u joints. The trucks was rattling while in gear and letting off throttle at higher speeds and it sounded almost like axle shafts bouncing around or something. It seemed to improve if you pressed the clutch pedal in. Now I was doing some miscellaneous work today and was in neutral and if you rev the engine to higher rpm I can hear a rattle but cant seem to hear where it is coming from. The rattle or knock doesn't seem in time with anything like a rod knocking typically sounds. it seems inconsistent. im not certain I don't have two different knocks going on. one that has something to do with the clutch or flywheel and one up front somewhere. I checked to try and find any play in serpentine or pulleys and didn't seem to see any. Truck seems to run and shift pretty well. Truck does seem to shake pretty good at idle though. any help would be much appreciated.

Our trucks came from the factory with the infamous Dual Mass FlyWheel (DMFW). These turned out to be problematic. The dampening springs that are normally found in the clutch disc are in one section of the DMFW while the disc is solid. You will probably need to remove the flywheel inspection cover and check things out and see if you have it still. First look in there and see if the dampening springs and the plastic retainers are all there. You also need to measure the distance the two masses of the flywheel can counter-rotate against each other. Measure at the flywheel outside rim (more than 5/8" and the flywheel is bad). At that point I would switch to one of the many available Single Mass FlyWheel (SMFW) and Clutch kits (I like the SouthBend Con-O for stock power levels). The kits are less expensive than just the factory DMFW. If you let them go too long you can actually crack the transmission case. Cheers!
