I've broken both grease zirks on the base end of the steering cylinders. One of them broke off inside the pin. I was unable to drill it out with a left handed bit so I ended up buying a new pin.https://www.dropbox.com/s/as5gu85aqw...%20Zirk.jpg?m, https://www.dropbox.com/s/nzp42ggk03...%20Zirk.jpg?m, https://www.dropbox.com/s/1k9hy8gwnl...%20Zirks.jpg?m
