I'm looking to put in new bearings and race. I've watched the YouTube videos. I'm looking to do it with basic tools, dead blow, punch, sockets, old bearing, whatever.
I don't have bearing pullers or race drivers. Any suggestions?
I already have the bike disassembled. Just need to pull the lower bearing off and on. And pull races out and in.

In a pinch you could use a cut off wheel setup to remove it but again be careful you don’t nick the stem.
The fellow above really has the best advice. Call around to a couple local machine shops. They’ll do it right and inexpensively.
The Shop
The outer bearing you can pry off or knock off easy so just the inner part is left. Use a Dremel with a really small cutting wheel to cut a deep notch into the inner bearing about 1/2 way through. Heat it with a small propane torch. Then use a punch and hammer in the notch to try to make it spin. The deeper the notch the easier it will be. Once you can get it to spin, it will come off easy.
Use the old inner bearing as as tool when installing the new ones.
