I would use a piece of wood and a heavy hammer to get it most of the way. as it gets flush with the knuckle, I use the old bearing race.
I would buy the kit if you want to do it 'easily', I think this kit helps get the hub back in as well, you have to be careful to support the inner race properly when putting the hub back in. I would love the kit, I just don't want to spend $200(they used to be $300+) Haven't done a wheel bearing on the jetta in over 3 years, so its not a tool that would get a lot of use for me anymore.
