How To Remove Pressed-on Bearings - EricTheCarGuy
http://www.ericthecarguy.com/ I know this one does not cover an entire procedure but it just worked out this way. I did however want to show how to remove this type of bearing should you run into it. I didn't show the installation for 2 reasons on this, first, I just didn't have the time to shoot it, and second I recommend pressing new bearings on rather than hammering them into place (I don't have a press yet). I would say that hammering them is OK but you risk damage to the bearing and if that happens it is a lot of work and more money to fix it. Be sure to wear your safety glasses!
