How do you get a bearing out of a 2006 crf 450r rear hub?

2 ways

Buy a good bearing puller.

Or knock the spacer that is between the 2 bearings sideways a bit and knock the bearing out with a long punch.

Get the retaining ring out and tap it outwards from the other side with a long punch.

That's how I did it on my yz. It's easy.

Just don't hammer on the inside race of the bearing when installing the new one. The best trick for installing bearing is to pop the new bearing in the freezer for about 20 - 30 minutes, then heat the hub with a heat gun until it's too hot to the touch. Grab the bearing and place it into the hub. It should either drop right in on its own or will go it with minimal pressure. Do this quickly so the bearing and hub don't heat/cold sink.

Isn't there a retainer on one side that takes a semi special tool?

This. Every time you drive a bearing in or out cold, using a drift or what not, while you may not see much to the eye, a bit of the bearing surface ,whether in hubs,cases,etc, is driven out with the bearing. Eventually, a loose interference fit in that bearing cavity will develop.

Mine had c clips on each side that had to be removed with this tool. I guess its called a c clip plier.
