Replacing Bearings in Y Carriage

Disconnect plug from X axis motor and end stop
Remove 3 m3x25 screws on the underside of the X axis motor. (note that this is not necessary if the nuts are in the nut catchers under the stepper motor - in that case only the M6 bolts in the next step need to be loosened to take off the motor.
Remove stepper motor to the side
Loosen the M6 screws on the motor side and the idler side to remove the X axis from the Y axes. Straddle the X axis on top of the printer.
Disconnect the plugs from the 2 Y axis stepper motors and one single Y endstop
Remove the Y axes
Release the belt by removing belt peg.
Remove the idler sides from Y Axes
Remove the carriages
Open carriges up and replace bearings.
Replace carriages.
Replace idler sides, but don't tighten the idler side yet. Place the Y axis back on the frame, and tighten down the motor side, adjusting the idler side as needed. After idler side is adjusted, then tighten down the idler side.
Re-tension the Y belts
Replace the X axis back on the Y axes, and tighten down each side with the M6 bolts.
Re-plug the motor plugs and endstops on the X and Y axes.
