Started looking at bearings because of this thread, and ran across this technique for diagnosing front hub bearings. I hadn't seen this before, so I thought I would share it.
" I had originally thought the driver side bearing was the bad one but using the Spring Test technique I figured out the passenger side was actually the bad bearing. This technique is where you lift the drivers side tire off the ground jacked by the frame, reach in and grab the spring with one hand, then spin the tire. If the bearing is bad you will feel a distinct vibration coming up through the spring. I felt nothing so I then lifted the passenger side front tire off the ground, held the spring and turned the tire and immediately felt a rumble coming up through the spring. So I took the tire off, caliper and brakes etc got the bearing in hand and yeah it was shot."
