Warn makes replacement hubs for the "5 bolt" ones that are on your CJ.They are probably a bit better than the stock ones. Otherwise you can convert to the early "6 bolt" Warn Premium hubs, but this requires the actual "Hub" and lockouts from a '81 (I think) or earlier CJ, or you can spend some cash and buy the conversion new from Warn for about $275. Check out 4 Wheel Drive Hardware http://www.4wd.com. if you don't already have one of their catalogs, go to the web page and request one...it's free!
