Try to re-do the whole the thing with brand new parts. Take your time, clean each part, then take some high grade sandpaper and sand the ball part(knuckle where the seals are at the ball part) till its smooth get all the rough edges and lines out any roughness will make the seals not be right and leak. Thats just my experince and dont forget to freeze this stuff in the freezer before trying it. If you dont believe try looking at 4x4 builder magazine dot com or their magazine it tells alot of info about rebuilding your toy front axle. Thats where i got that info. Good luck.
