3D Printing: Screeching Noise when moving the Z-Axis Down


The Question: I have had my Prusa i3 clone for about two years and it has always made a
screeching sound when the z-axis is moving down. I have tried many solutions
for this problem like greasing the z-rods, printing a new top part (the holder
at the top z-rods end) with a bearing to prevent the threaded rod from swaying,
and even hot glueing bearing to the stock top piece. However, none of this has
worked. I am not sure if it is affecting the print quality but the sound is
very annoying when it is doing a lot of hops and I would like to fix it. Here
is a video (with sound) of the rod moving up and down.
