At first the damage seemed confined to the end caps and flange. After removing the right steering axle, we found the pivot axle was damaged resulting in ordering additional parts.
Total time to repair approximately 5 hours after removing the hood, and both tires, r and l axles, and the pivot axle.
Your schematics were helpful in removing and replacing the damaged parts.
