CSfiend, that is a cool trick with the coil spring. I will have to try it.
I have to say that I have had really bad results locating the bad wheel bearing by road tests. I have been fooled twice this way. What sounded like a bad bearing on the right side of the car (noise on left curve) turned out to be a bad bearing on the left side. It turned out that the bearing was louder when UNloaded. Why this is, I don't know. Of course this mistake costs half a day and $120, but the good news is you end up with two good bearings!
