Installing Inner Oil axle seals

This is for my waggie front end. The original seals didnt have a real lip, and the new ones are no differnt. But there is a second lip on the inside that is stepped down from the edge. The arrow in the pic is pointing to it. Well i am going to try adn seat the seal with this lip. Problem is i already tried it on one seal and mangled it, but then again, i first tried to tap it in. I have a socket that fits just inside the seal and fits on the inner lip. Well i believe i tapped it in cockeyed first. I did this with a little hammer on the socket. But then went and had a steel square rod that fit the socket hole perfectly. So when i was hitting it with the rod going throguh the housing, i dimpled the inner rim by tapping it in badly.

Well it is time for the second seal. My question is should i be using this second lip or is this a bad thing? The wat the seal goes in, i cant get onto the outer lip. Any suggestions? I am going to get a buddy to help me for the second seal.

 

i have a smaller piece of threaded rod. just avoiding buying a longer piece, i might have to weld something together. Oh well, glad i am not the only pweson who has done this

thanks!!
