Any reason why the x,z and extruder stepper motors are silent but there seems to be an awful lot of noise coming from the y (bed) stepper? reminds me of my original ender 3 with the 1.1.4 8 bit board.
Ensure the belt on your Y axis is not loose. On bed slingers it is common for the Y axis stepper to be slightly noisier due to the fact that it is moving the whole bed back and forth.
