Just tap the end of the spindle to knock out the bearing on the opposite side of the wheel, use a nylon head hammer, or other soft tool to avoid damage to the end of the alloy spindle. Would also be a good idea to remove the cassette before you start as I think the lockring will stop the bearing coming out.
Make notes of what you remove from where as drive / non drive side parts are different sizes, also the spindle only fits one way, from the non drive side.
