Gmwillys was right. The axle has been changed. Somebody removed the factory axle, probley a Dana 25, and installed a Dana 44 spicer. The Dana 44 is a much better axle so this was a plus. Had trouble finding grease grade 0 which must be used on the front wheels. Had to special order it at 25.00 per can and it took two cans per wheel. As soon as I hook up the power steering I will be finished.
