Is it normal for the inside of the bushing seat hole to scrape the king pin and get worn when you are pulling it out? Whenever I flip my hangers for whatever style of riding I am doing the kingpin is chewing into the hanger on the inside of the bushing seat area. It is wearing a notch. Is this normal? It happens on both trucks. I know the kingpin is harder than the hanger and the kingpin will win this fight but I am wondering if this is how it is supposed to be. This doesn't happen on my Paris trucks.
