I am wondering if my windshield wiper transmission is OK as is or needs attention. All of the three ball and socket joints are very free moving. All of the rivets are tight but there is no resistance to movement whatsoever. Two of the three joints have almost no play in the joint. Meaning when I try to move the ball around inside the socket, there is only the tinyest, barely noticeable, movement. The third joint however has some play. Maybe a little more than a 32nd of an inch when moving it side to side.
Is this normal and OK or do I need to do something about the joint with the play in it.
Should you use anything special to lubricate these ball and socket joints.
How about the rotating joint of the the wiper post. Does that need to be cleaned and lubed in any way. They rotate freely with a little resistance. I don't know if that is normal or not.
