I took it off and replaced it. I split the carrier bearing to see what it looked like inside. All the balls seemed to be round except one and I probably caused that, touching it with a cutoff wheel. No grooves, but it evidently spun it around a few times. The outer race also looked pretty smooth, but there was a little variation in color like the one side was getting loaded heavier than the other. The inner race didn't show anything out of the ordinary. It is quieter now. Now I need to add some felt that I retrieved from some other car that got junked to do some sound deadening. It is a wagon and they are a little noisier than sedans due to no barrier behind the rear seat. I realize they are a cheap car, but I should be able to quiet it down a little.
Thanks for the replies, Roy
