Let me just throw this out there: The first time I jacked my vette up to check the rear wheel, I jacked it up by the frame in the back. When I spun the wheel, there was noise and resistance, I thought my bearings were shot!! It turned out that when the car is jacked up, the wheel swings in a bit when the spring is not compressed and rubs against my parking brake cable. When I jack it up with the suspension still compressed, the wheel doesn't swing in and doesn't hit the cable. So just make sure that's not happening when you're checking your wheel.
