xArm6 Joint 4 not working

1

The 4th joint of our xArm6 started to jitter suddenly, the problem is essentially the same as here: Xarm one joint not working
TCP payload is 0.88kg. The problem occurs with cooled motors. When putting the robot into “Manual Mode” backdriving the 4th joint feels abnormal (compared to other joints - more jittery resistance).

How can we fix this?
