ABS and Brake light are staying on, but more over, When I replaced the left side axle, it was not going in over the ring pin. I took off the ring and placed inside the new axle (in the groove of course). It was still not going on as easy as it should so I used a hammer and "gently " tapped it in. I believe it seated, but now it appears to be leaking. Not sure if I damaged the seal on removal, or did some more serious damage forcing it in place. Can any damage occur that way?
