Motor started making clicking sound

Altmill making noise as gantry moves front and back ??

Guys this morning my right Y motor (side) started to make a clacking/clicking sound as it goes back and forth. It follows the speed of of the gantry movement , faster it moves more clicks you
hear at a faster rate ??

This started on day 3 .
I reached out to customers service as well

Any ideas ??

Thanks
