Outer Limits 4x4 Board

my hi mount leaks oil where drum goes into caseing, its just been rebuilt any good mods you to recomend?

If it was rebuilt with a new seal (the square sided one) then its probably pitted where the seal runs.
Some people have used two seals side by side, but a better fix is to lathe up a groove beside where this runs and fit a secondary round oil seal running inside the bush, problem fixed.
