It's been a while, but I'm back with another question. I could barely hear myself think in my '86, the tires are howling that loudly, and a tire shop manager asked me if it might be a rear wheel bearing. I said, 'Naw, not my car'. So, I hit the open road and do the turn to the left, turn to the right test to see what I could hear. Lo and behold, when I turn to the right, the howling briefly goes away. Turn left, noise stays. So, have I got bad tire alignment, or a bad bearing, or is something going south in the dif? Your comments and experience eagerly anticipated.
