UM 2 making a creaky sound

[leoddc 73]

Hey guy's, long time no post 😄
I have recently noticed a creaky sound from my UM 2 when the printer head moves left to right. I have lubricated all of the axis rods so I think it's coming from the motor. I've attached a video here but the sound isn't very clear. Can anyone help me with how I can fix this?

So I've seen several printers that do this - they are all old.  They've all printed kilometers of filament.  I think you can safely ignore it for another year or so.

 

I've heard some people say that the plastic that holds the motors bends slowly over the years and then the belt isn't as straight as ideal and the noise somehow comes form the belt maybe?  Or from the steppers?

 

I don't know but I know a few printers that do this and they still print great.

 

If you push the head around by hand and listen, then loosen the 4 screws that hold the motor in place the sound goes away.  That still doesn't tell me what causes the sound.  It could be bearings, motor, or belt.

This video talks about a kind of similar sound, maybe, of an Ultimaker clone. I don’t know if it might apply here.
