King do videos on their site. Undo the axle with two 5mm Allen keys. Turn the free hub body and pull, it will come out with the axle. The ring drive should be run on King drive lube, but it can be run on oil (king recommend tri-flo for winter running). Without the hub adjustment tool, you may have problems adjusting the bearings, unless it has the Allen key on the non drive side.
Thanks for this , really helps , I was able to clean and lube the ring drive with the main bearings in, the freehub body needs a good pull to remove , I cleaned all the crap out and lubed with CK lube, the freehub body needed a good push home to locate it. The being adjustment was simple with the 4 hole adjuster. The hub now sounds a lot happier and like it used to
Thanks once again
