[Barrier Blue]

I don't know if this would help you with your problem, but it may help others. A couple years ago my upper bearing was noisy when I would turn the wheel, like clicking and grinding, and sometimes it would catch a little, and would require extra pressure on the wheel to turn it. I thought I was going to have to find a replacement, but thought I would first see if I could fix it. I removed the wheel and got access to the bearing. I put my needle grease fitting on my grease gun, and squeezed grease all around in the bearing, put it back together, and it was fine. One of those rare instances where something worked out easily, and at no cost.
