If the noise only happens in the spin cycle it may be the bearing but the most likely source of the chirping noise is the brake.
The brake rotor and lining may be rubbing together after the brake is released for the spin cycle.
While the brake rotor and lining 21002010 is not very expensive ($20 dollars) I would recommend a technician do the repair. There is a brake tool that must be used to take the brake apart. Trying to release the brake without the tool can lead to serious injury. The brake tool is very expensive so it makes it's difficult to save money on a do-it-yourself repair.
One thing you can do is to remove the front panel and see if the source of the chirping sound is more obvious. See the image below for how to do this. Other sources of the noise could be the belt/pulley and/or the pump.
I hope this information is helpful to you in completing this project but if you can submit another question with any additional details for further assistance.
