I’m also wondering if a bearing on the input shaft of the trans could be damaged. Regardless, it sounds like you will have to pull the trans and see what’s going on.

This is going to be your best bet if you can not see anything obvious.
You may have some un-wanted metal to metal contact going on around the clutch area also.
Keep us posted.
I can’t tell if it is increasing with rpms simply because of the engine noise, But i can say that i can drive the truck fine, gose through all the gears fine. It dose not struggle to go in gear or out of gear so i’m thinking it’s either piolet bearing or the throw out bearing. But to me it seems odd that it take time for the noise to come on, today it probably idle for a good ten minutes and i even moved the truck and then it started to make the noise. It seems like if it were a bad input shaft bearing it should make noise constantly.
Well now that you have stated the noise only occurs AFTER the truck has been running for a period of time could be related to another issue.
Metal expands with heat.
How often was the vehicle driven after you first installed the engine?
I was only suggesting the input shaft bearing if maybe there was a problem lining the engine up and it banged into the input shaft and damaged a bearing. As dreamer said, I would rule out the throw out bearing, as the noise would not be present when the clutch is engaged (foot off the pedal) as the bearing would be pretty much sitting there motionless at those times and not in contact with the pressure plate, unless… and I just thought of this… Unless the clutch pedal needs adjusting because the throw out bearing is probably in contact with the pressure plate at all times. In fact, now that I think of it, that is more than likely a cable system. Did you back off the clutch cable when you replaced the clutch?
My guess would be a throw out bearing… If it was me i would drop the trans again and spin what ever parts i could to see if i could hear the sound.
Did you double check all toques and specs? are you messing any tools lol??? are you 100% sure everything is mounted flush?
Yes i’ve got my tools and my torque settings lol. But the throw out bearing makes sence but wouldn’t there be a consistancy to the noise?
Check for clearance issues regarding the exhaust and drive shaft. since you just had exhaust work and then it started.
Good thinking, i’ll get out there and check and see, but somehow i dont think it is, had a reputable shop (and a friend) weld it up for me but could be the case.
Still nothing. check all the bellhousing bolts, went through the exhauste nothing was loose or rattling, i’m thinking piolet bearing or throw outbearing even though i just replaced both.
Does this noise level increase as the RPM and speed of the vehicle increase?
Its interesting if was fine before you took it to the exhaust shop and now you have an issue.
I would also rule out the throw out bearing as you would only hear that noise when the clutch is depressed.
I think at this point it’s safe to say the trans has to come out so you can inspect the clutch an it’s components, we can speculate all day but sometimes you just have to get in there and put your eyes on the problem. If the noise is as bad as you say I’m sure it will be easy to find once the trans is out.
Well i will try adjusting the clutch linkage and see the noise gose away could be adjusted wrong i have not touched it. But if thats not it i’m dropping the trans and seeing what’s up. My only thought is it may not be that easy spot because of the rate that engine and trans are turning at, so it would be hard to get the same noise but only work will tell me, thanks for all of your comments every one i’ll keep you updated.
If the cable was adjusted during the life of the original clutch, then yeh, it’s probably not going to fix anything. If it wasn’t however, and you installed a new clutch like you said, then it’s possible that the cable is too tight, holding the throwout bearing against the pressure plate fingers. I was pretty much thinking as I was typing, obviously. Keep us posted!
