THIS IS FOR A TRAILER - i need to determine what trailer hub i need

What is your question?

the length of the spindle is 2.5 inches( not including the threads) the length of the spindle INCLUDING the threads is 3.33 inches the diameter of the axle is 1.25 inches the diameter of the threads is .95 inches i have tried a few hub kits ( i would like to use a pre-greased kit) but the only one that fit was too long and would not leave enough room for the castle nut and pin id rather not fit a bearing kit just the whole hub kit i have no experience with this. is there a " short" hub ?? helppppppppp thanks
