Hi John,
I just replaced the ball ends on my power steering cylinder with
ones from McMaster Carr. I got the ones with the grease fitting and then added these
rod end seals to help keep the dirt and grit out. One thing I found during the install was that the bolt which mounts the cylinder to the tractor frame was a little short after adding the seals so I needed to get a longer bolt. Overall they are working great and the new rod ends eliminated a lot of the slop from the steering.
