When I fitted my hardchrome kingpins I removed the remote oiler and rather than fit top grease nipples I just fitted a bolt to plug the hole in the top kingpin bolt. I only ever grease from the bottom nipples about every 1000 miles. Everything's been fine for >50k miles now, so I'm happy. I'll probably re-do the kingpins and bushes some time in the next few years, then it'll be enough to see me out.
In my opinion nothing in the front suspension comes anywhere near the importance of fitting hardchrome pins when it comes to longevity and ease of maintenance.
