6 years after the lower kingpins sat in flood water, they failed. So far only one needed replacement. Replacement was limited primarily to the bearing and kingpin itself, but there was severe damage to the knuckle hub and a little to the axle casting from the castings rubbing on each other.
The new lower kingpin bearing seal no longer fully contacts the original hub bearing cavity, so installed that seal and added a zerk fitting to allow grease to be inserted into the bearing area, pushing out debris or water that might occur in the future.
The knuckle axle joint (double u-joints) also showed some missing paint because it had been rubbing on the knuckle casting. The rubbing was caused because the axle was running lower than designed due to kingpin bearing disintegration.
