Bearings

I was once again at my favorite car mechanic to check out a strange noise I have been hearing for a couple of weeks. In my best Spanish I told him the car went hmmmmmm when I drove down the road. He immediately jacked it up and started rattling the wheels. Sure enough the back left wobbled like it was ready to come off the car. I'm not sure if it was a bearing problem, obviously others had issues with them as these were laying around the shop, but when I returned four hours later everything was fixed and my SUV was ready to roll (silently for a change).
