[Diagnosing a Jeep T4 Transmission Noise]

In do not have a dial indicator but everything feels tight with no end play. The reading while turning the input shaft  with a torque wrench is within the  spec on the t4 video you provided. The pilot bushing is new and seems to be a good fit. I'll have to double check on any play with the mainshaft tomorrow and report back. I have the clutch throw out bearing etc out. I Will reinstall and check that for play but if remember correctly it did not have much play. Thanks again for the help. This forum is awesome.

Thank you so much for your response and suggestions. Yes ii have put a lot of work in this Jeep and im ready to start driving it. I apologize for the first video of me turning the shafts. I did not have the rear housing on it that keeps the preload on the bearings. That is why it looks like there is so much side to side play. I made another video with it all tightened up posted below. About the bearing retainer. I did put shims back when i replaced it. I have also tried differnt sizes and played with the end play but its stil sounds  the same. I have another T4 that probably needs to be rebuilt. It sounds about the same.

And here I have the cover off and turning it by hand. I'm not sure if it sounds normal.

Here I have the rear wheels jacked up, the trans is in gear and the clutch pedal depressed. Not sure if this is normal.

 

 

[Diagnosing a Jeep T4 Transmission Noise]

I need help figuring out a noise that's driving me crazy. First a little history. I have an 83 CJ7. 4.2 and T4. I bought it about 5 years ago and have been restoring it since. I have done a frame off and replaced almost everything (ujoints, bearings ball joints etc.) It has a new bds 2.5 lift and m.o.r.e shackles that give it another 1/2". When i bought it she ran and shifted pretty good. Its been 5 years but im confident i did not hear any noise in the transmission before.  The only thing i did to the T4 was clean it up and changed the bearing retainer with a steel one beacuse the old aluminum one was galled. I got it all back together and running good but it has a noise. The driveshaft angle is too steep  so i thought maybe that had something to do with it. I tried driving around with just the front shaft in and it still made the noise. I'm going to get a double cardan shaft for it after I figure this out. It only does it with the clutch pedal depressed and the transmission in neutral while coasting. Can also hear it between gears when shifting. I took the transmission to a reputable guy who rebuilt it with all new bearings and brass synchros. I put it back and noise is still there. It really sounds like it's coming from the transmission  or in the bell housing. It also has new Luk clutch, pressure plate, throw out bearing and flywheel. After only a few miles of driving it around the block there is small metal flakes in the oil. I know some is normal but that fast?  Any help is greatly appreciated.  Below is YouTube video of the noise.
