So if I'm reading the book correctly the oil seals for the front axle on my cj3b it's a Dana 25, they are located inboard of the axle tubes near the third member. They have to be replaced after pulling the third member I assume? Never did anything like that can you walk me through it? I'm sure there's some shims that have to be taken care of if I don't change anything else but the seals can I just pop the third member out, change the seals, and replace it with out changing any of the clearances?
