re600 bearing problems

Hello to the group. I am a long time woodworker and was browsing the internet on info on bearing noise with the re 600 ryobi router and came across this site. I thought I was out of luck in getting replacement bearings for my discontinued router until I read a few posts here.
Is it a simple matter to replace the bearings myself? If so does ryobi supply new bearings or must one go elsewhere to get them? Sources?
