Noise from transmission / transfer ? (1 Viewer)

[618Henrik]

Got a weird sound from somewhere around the transfer case. Tried to film it.
It appears to be the same sound as in this tread Name that Tune!! (mystery cruiser noise) with video - https://forum.ih8mud.com/threads/name-that-tune-mystery-cruiser-noise-with-video.1111829/ But there is no conclusion in there.
I have tried the following:
Driven without front propshaft
Driven without rear propshaft.
Driven the car with the centerdiff locked
Driven with transfercase in LO
Changed fluid in the transmission (only part of it, did not do a flush)

Noise still there. Not sure if am facing a transfercase issue or a tranny issue? Its a HDJ80 from 1993 with the A442F

Any help would be appreciated

have taken the transfer apart. Found a bearing that might be the source. A tapered bearing for the idler gear. Looks a little bad and maybe if the preload have become to light the outer race will sometime rotate?

Has your transfer case been apart/worked on before?

I don't think so.
I have had the car since it reached 300.000km, now it is 475.000.

Update; Bearings in transfer changed and with new and correct preload shims. Car runs greath, but the wierd sound is still there
