Wheel Bearing Replacement

Hi again everyone,

I am back again for more advice. This time it is regarding the FRONT OFFSIDE wheel bearing on my wife's 01 Ford Focus 1.8 Zetec estate. It is grumbling like a bugger and I would like to know is this something I can change at home or does it require a press to seat the new bearing properly.

Thanks to all for your help in the past,
Yours,
