I just bought a brand new set of WARN 30 spline drive flanges part # 39340 from Rubicon Outfitters For my Dana 60 or so I thought. /forums/images/graemlins/rolleyes.gif These things are way to small for my hubs. They fit that axles fine but will not engage my hubs. Do I need to upgrade my 60 to 35 spline outers and then get 35 spline flanges? Is the set of hubs I got designed for a 44? Why don't they say that? all they say is 30 spline. /forums/images/graemlins/angryfire.gif I just spun my Milemarker hubs and I thought flanges would be the way to go. Does anyone make 30 spline flanges for a Dana 60? I would appreciate a link or 2 Thanks.
