Sound Coming from the Motor Bafang BBS02

[Pabulous]

I just noticed a sound coming from the motor. It does not sound that loud or even cannot be heard while riding but I just got worried. Does anyone had an issue like this? What is the problem and the solution? Thanks in advance to everyone Youtube link:

Change bearing from motor shaft, how?

Hi I've just unscrewed my bafang mid center motor and found that a faulty bearing is causing a loud noise when the engine is assisting with power to my ride. Before I do anything by myself, how easy/hard is it to change it? Is there any special tools needed? Or should I let a workshop do this...
