Grinding sound from rear end area when driving

[Crawdad]

I got off early from Drill today and jacked up the rear with motor off and in park. Once on blocks I released the emergency brake. At that point I turned the the driver tire in a clockwise direction, the passenger tire was going counter clockwise. The grinding noise Was coming from the passenger side wheel. The hothead, transfer case, and driver side was all fairly quiet. Guess its the bearings. Is this something I can do or should I get a pro? Will look around for tech articles.
