Thanks for the replies.

I have a 12 ton press (harbor freight) so I should be all set there. I agree with the idea that it may not feel bad while under no load. Also, the new bearing is much stiffer than the old one; they both rotate smoothly but the old one has almost no resistance at all. Might be a sign of something?

I did not check runout. To be honest I don't really know what that is or how to check it but I will look it up right now. The sound doesn't really change when turning as far as I can tell. And if it ends up being that I fixed the wrong one, well I will feel pretty dumb about that lol.

As for fight now, I didn't read enough before starting the job. I don't have any snap ring pliers that are anywhere near strong enough to get the ring out of the spindle.
