I think my rear wheel bearing is bad on the driver side, I looked on eBay and the whole wlhub assembly is cheap. Is this a straight forward repair? I have also noticed that if I have been driving awhile and turn it off then start it back up fairly quick the temp red light flashes a few seconds then goes away. At no other time other than first starting after a long time a blue light comes on do I have any temp lights.

 

YouTube or find an exploded parts view for the hub and just analize how it's assembled

 

Fixing the hub is easy and straightforward. There are tutorials on YouTube.
The blue light just means that your engine isn't warm enough to run "good". Basically it's meaningless IMO.

 

Replaced both rear wheel hubs last June in my front yard with floor jack and simple hand tools. Made a world of difference in road quietness. Definitly replace both at the same time, now I need to replace the swing arm shoulder bushings. I got both bushings for $58.50 off Ebay, make sure you get the sensor model (has wire plug in on back)..You can do it.
