Truck is a 1990 4wd pickup. Alignment shop said they could not align correctly due to wheel bearing play on the driver's side. Took it apart today, and yes, the tapered outer bearing seems to be toast. Inner bearing looks and feels fine centrifugally. It does move in line with the spindle axis but I assume this is normal? I don't want to wreak a good seal and bearing if I don't need to.
