Iseki LandLeader bad sound

Hello guys, there's a bad sound coming from the front of the tractor. We opened the front axle and changed the 2 bearings, one was shattered. The sound kept coming when we drove the tractor. Any ideas what may be the issue? this is the sound, at first it appeared only when 4wd is engaged, now in both 2 and 4 wheel drive. VID_20210524_111939.mp4

I could be almost anything. I think you need to jack up the front and rear and block it up so you can turn the tires one at a time and see if you can tell what is making bad noises. If that doesn’t work, while it’s blocked up securely, run it in 2WD and 4WD and try to isolate the noise.

There is a clunk noise in there, but hard to separate it from the normal diesel rattle.
A cheap mechanics stethoscope is a length of pipe or a stick held near your ear on 1 end (take care not yo drive it into your ear, place your thumb between it and your ear). You can slide the pipe along the axle housing to get a better feel for where the noise is coming from.

A wild guess is 2-fold:
•a piece of bearing material is caught in a gear tooth of the drive gears and causes the noise when it is encountered
•with the bad bearing a gear was damaged and when the damaged area is encountered you hear the noise.
These are both purely speculation. If the stethoscope locates the noise to be somewhere other than in the area near one of the bearings, those guess are worthless.

The OP ended up finding the noise and posted on another thread. Turns out the ring gear could use a dentist...
