I replace my Hope BB bearings by putting the BB in the freezer over night and then popping it in a cup of boiling water. The old bearing just drops out as obvs the Alu cup expands quicker than the steel bearing. I then just push the new bearing in. Can you do something similar with the wheel? Poor boiling water on the hub, or warm it with a hot air gun so it expands a bit?

I need to replace the bearings on a Goldtec rear hub. I've done it once in the passed but managed to mess up the axle and destroy one of the new bearings, so I'd like to do a better job this time.
The main issue I had was pressing the new bearing in, the tolerances seem tighter than I'm used for bearings and the method I've used in the passed for my phil woods won't work as the axles are solid with the Goldtecs.
I'd like to get a cheap bearing driver kit £20/£25 tops but what should I get ? the concern I have is all the examples I've seen of a bearing driver being used are for hubs which don't need the axel in place when your fitting the second new bearing. So the driver needs to be able to clear the axel end and allow you to apply the pressure required to drive the bearing into place. Hopefully that makes sense ?
Does anybody have any advise / suggest of the best tools to buy ?
