I have a few questions, I will call champion trailers tomorrow but just thought id get some ideas from people here, I bought their spindle lube axle with hubs, all galvanized yada yada, but i noticed a difference in the castle nut it has two washers under it one has two tabs on it that protrude from within the castle nut is this a new way of eliminating cotter pins? do i just set my castle nut and then bend the tab on the washer outward ??? I guess its hard to explain unless someone has seen it already before. <br /><br /> My second question is i notice theres a fitting at the end of the axle for you to put a grease gun on for the grease to go to the inner bearing, if i use buddy bearings should i remove that fitting on the end of the axle to allow grease to travel easier from within the spindle?<br /><br />Thanks alot <br /><br />Paul
