Sound was from front left. Tech at dealer could not find any unusual wear, but said brake dust was pretty heavy, and might be the culprit. This was Friday of last week. I did get a chance to go into 4-hi Sunday, and slog through a bit of muck. Since last post, drove about 40 mi./ on interstate, and couldn't hear it. Maybe he was right, and the water cleaned it off. [Huh?]
Thanks
