no press needed, just a large socket 30ish mm and a large hammer, then use a vice to press them in
I would suggest getting someone to press the bearing. You won't remove the old one with a socket and hammer, unless you are lucky.
You may be able to fit the new one with a vice, but its alot easier with a press.
Also if the mk4 is anything like previous models, you will need a knife edge puller to remove the bearing race from the hub.
Not really a job for a novice.
