Default C5 - 1998 Manual Transmission Problem

at 119,000 miles I had some noises start to emanate from I think the clutch plate area so had the clutch plate, disk, and had all the bearings done in the torque tube. Also had the clutch piston replaced as well. Got it back and been driving around and I am getting more noises similar to before all the work was done but this time I did more experimenting with

"sometimes" it will start making a grinding noise quite loud even with the clutch fully depressed
If I shift into neutral release the clutch then depress the clutch then try to put it in gear it goes in some of the time without the noise other times I have tried 2-3 gears and it still makes noise
If the clutch is depressed after the noise and then shift to neutral and leave the clutch depressed it consistently and in any gear I try starts grinding

I attached a video ( I hope) that you can listen to the noise --- any help appreciated

Just to be clear, you replaced:

-Flywheel
-Clutch
-Pilot bushing
-Throw out bearing
-Slave cylinder
-Torque Tube bearings
-Torque Tube couplers

Were the torque tube components checked for runout?

yes to all the replacements above and I’d have to check with the mechanic on the runout (exactly what does this mean?)

update took car out today drove it hard over 30 miles stop and go high speed slow speed and the grinding never occurred? It appears to be intermittent and not all the time???

Thats a mechanical issues. It will show its face again and maybe comes back with vengeance when your driving it hard, I had a grind that came and went. Stopped grinding and there went my TT Cost me 10 times more because of that. Well, this is just me. But you know, i was thing that there might have been a bolt or socket left in there and ground it's sefl out, so you probably got lucky..
