Rear stepper motor replacement...

[Damenc]

I'm thinking of replacing the rear Z axis stepper motor, it's making a weird noise. I have the Geeetech A10 GT2560 V4 printer. I took a photo of the stepper motor label but can't find the SKU # on their site, anyone know which motor I need or does it matter? When installing it, are there any tricks I need to know? Thanks in advance. See linked photo for the stepper motor I need.
