So that's why one of my aftermarket pivot pins was super tight. I was dumb when I installed it years ago and instead of dressing down the pin a tad for a semi-tight interference fit, I ram-rodded it into the k-member with the nut and now it's really stuck in there. Some day I'll have to get it back out and I think the only way will be with some kind of horizontal jack device, like a bottle jack or something.
