Loud Squelling coming from bell housing

While the jeeps warmed up I'll be coasting in neutral and out of no where you could hear this loud squelling that comes and goes. To process the elimination I started narrowing down everything in the bell housing. New clutch kit Includes clutch disc, pressure plate, Pilot bearing and internal slave with bearing its all new I also resurfaced the flywheel and rebuilt the trans and that comes with new bearings in the trans . I can hear the squeling right under the bell housing while the jeeps on in a complete stop in neutral. I crawed under and put my ear near the bell housing and I could hear it more on the housing than anywhere else. If anyone out there had a similar problem and fixed it. Please fill me in willing and able to do whatever it takes. Thanks for reading

stethoscope

Pick up an automotive stethoscope. Us it to pinpoint just where the squeal is coming from. May not find it exactly but may be able to pin it down closer. Handy tool anyway.

Did the squeal change after any of the work? Can you put a pry bar under the tranny and excert side/up pressure and create/change the squeal? Does putting pressure on the clutch change it?

Try and separate any causes, write them down and eliminate/confirm one by one.

Get very methodical in your trying to analyze what is causing it. You may have to find it just by the process of eliminating everything else.

Throwout bearing. LOL, looks like the ONLY part you didn't replace. Could also be the bearing behind the retainer in the front of the transmission, but it is not likely. Bearings love to die noisy deaths.

That was one of the first things I did. I can't hear it with the stethoscope but just by ear I can hear it directly at the bell housing. It's like the sound is being covered by the bell housing. Thanks for the input though.

Oh. You have the internal slave. I forget about those since i converted to external when i swapped my AX15 in. Still though, might be riding on clutch. Bearings squeel and scream because of the heat and things that cause them to start seizing while they are spinning. If you had an external you could pull the slave off and see if it still screams. I don't know how to check that without pulling the transmission. You might be able to remove the inspection plate and use a mirror to see if it is up against the clutch. There is also a bearing behind the bearing retainer on the front of the transmission in the bellhouse. Depends on how many miles and how well you treat your transmission on of it is that. Even with a new throwout bearing the odds are still that has something to do with it if it is screaming.

Since you mentioned it, I want to convert to external but I'm a little confused about the whole set up. I have everything including the fork, bell housing bearing retainer ext ext.. but the slave and the master is the confusing part. When I eliminate the internal slave can I just buy the external slave and connect it to the original hose line? Do I have to buy the pre assebled master and slave together with hose line? I noticed the assembly doesnt have to be bleed. I have the pre assembled clutch master and slave but I just pulled it off another jeep is it still reusable??

Honestly in regards to bleeding the slave I am not sure and would not want to steer you wrong. Mine was external slave AX5 when I bought it. I swapped in an AX15 that when I bough it was an internal slave, so I converted that over and used my existing external slave. The standard parts it seems you have are the different bellhouse, throwout fork, new throwout bearing style, and bearing retainer that has the sleeve for the throwout bearing to ride on. I do know the standard way of doing it though is to just buy a closed system with the master and slave and install it. That is the only part I never had to mess with.
