I have a set of 170 bindings and have used them for 4 seasons. I have noticed the steel U fork is starting to seem a bit loose. When carrying the skis in my hand the fork rattles in the binding. I have seen some recommendations to replace the Ti fork but not the steel. It doesn't rattle a ton and it just seems like the steel fork has worn into the Al housing a bit which should be expected. Have you seen any issues with this or thoughts?
