The bearing DOES have to be pressed in; after removing the brakes and the front axle shaft, the wheel hub has to be pulled off using a slide hammer, then the bearing can be pressed out using a wheel bearing press tool, which has special sized cups that allow the wheel bearing to be pressed out and in.
You would have to purchase the correct sized cups that are specific to the bearing size, this will be costly, especially if they will be used for this one job. I would recommend leaving this one to a repair shop that has the tools.
I have provided you with the instructions for the bearing repair also:
