I put the rear end up in the air tonight to adjust the parking brake, because it isn't holding on an incline. After taking the wheels off, I noticed that I can barely turn the right rear rotor by hand with the e-brake all the way off and the tranny in neutral. I tried the left side, and it turns with a moderate amount of effort, but noticably different from the right side. So, how much effort should it take? I was planning to take the halfshafts out and replace the ujoints. Could they be the issue, or does it sound more like a bearing problem?
