To remove the Y carriage, loosen the 2x right side eccentric nuts with a 10mm wrench and slide the whole Y carriage out of the 4040 extrusion.

I found out after this point but I ended up having to replace the Y stepper mount because it got a "little" warm.

Remove the X stepper cable and Y endstop cable.

To remove the Y stepper motor remove the 2x M5x12 button head screws on the bottom of the stepper mount.
