I just put some new dana spindles for the larger inner bearings and some later model hubs on my D44 axle. Noticed grease is leaking out between my MileMarker hub and the wheel hub... I used brand-new Orings on the hubs from milemarker. I'm thinking about going to a hardware store and seeing if I can get an Oring that will fit around the milemarker hub so it'll seal up between the milemarker and the wheel hub. good idea? bad idea? I think it's worth a shot.... i want some input.
