If it is loud & noisy when on spin then yes it will be the bearings needing to be replaced. To remove motor, undo the nut holding the rotor bowl & pull rotor bowl off. Inside that you will find the copper winding stator. This is held in place by 4 bolts, after removing bolts you can then disconnect the 3 wires for the stator windings (red/blue/yellow from left to right) and unplug the rotor position sensor. You can then see the lower bearing but it probably won't help much as it is usually the top bearing which gets rustiest & noisiest.
