Between the pitman arm and the idler arm is an adjustable link. Both of the arms have balls on them and they fit into two sockets on the link. The sockets have adjustable screws on each end with cotter pins to secure. They also have zerk fittings to keep them greased. The seals on mine were all torn up and I need to get some new ones. But I can't find any. Any ideas where I might be able to find some? Thanks.
