I did hear the leveling valve leaking and crawled under the truck and found the long rod coming down from it had play where it attaches at the bottom.Tried to tighten the bolt at the bottom of that rod but it wouldn’t move.Going to have to cut it and put a new bolt when I finish my shift.Zip tied it we’re it doesn’t have any play for now.
