if that doesnt work you need a hydraulic press... take the hubs to a wheel place and get them to press it out and press the new ones in (if thats what you are doing) i had to gas ax the race off mine
I did this yesterday. Its such a messy job without the right tools i.e. press and/or puller.
Had to grind both a shell off, that was trickey without damaging the stub axle, basically a lot of bashing and heating the hub/freezing the new bearing shell for the rest
