A linear seat recliner adapted to interconnect a seatback to a seat bottom and which is equipped with a recliner rod assembly having a recliner rod and a ball joint mounted in an aperture formed through one end of the recliner rod. The ball joint includes a ball swivel having an arcuate outer surface which is retained within a socket defined by a pair of retainer rings mounted in the rod aperture. The retainer rings rotatably support the ball swivel within the rod aperture to permit relative angular movement therebetween. The ball swivel further includes a throughbore adapted to receive a hinge pin for securing the ball joint end of the recliner rod assembly to corresponding structure of the seatback or seat bottom. Crush ribs are formed in the throughbore of the ball swivel for engaging the hinge pin and establishing an interference fit therebetween.
