Hello everyone. A tip, I don't know if it's a problem. The grease comes out of the vent holes. It has no leaks from other parts. Is this normal? Strange . I attach a photo . Thanks

    I'd guess the seals are leaking and the adjusters need to be rebuilt. Maybe someone has over tightened the tracks and blew the seals?
