Printer noises

hey guys,

been using this printer for a while now, and noticed a lovely rattling noise (mainly when doing infill, to a point i can hear it across the house,

when i look into it further it seems to stop if i apply a bit of pressure on the two iglidir bearing on the rods that follow the Y axis,

can only think to change them out as they appear to wobble a little when printers stopped i can manually move them slightly,

any ideas? if this is the case has anyone came up with a fix?
