OK, I think we can collectively agree that the lock washers don’t belong and I need to replace with thick flat washers and the castle nut doesn’t engage with the cotter pin. It’s purpose is strictly as a fail safe.

OK! Now Jerry’s point on different grade fasteners brings up another question. The bolts in question on my 52’ 1/2 ton are 1/2”-20. I made the assumption that they would be grade 8.

Are they grade 8?
