The hydraulic steering cylinders on Mr. Case, our old loader/backhoe, were starting to leak, and the ball joints on the cylinders had some obvious play in them, so it was time to overhaul the cylinders and replace the ball joints.
I took them apart for inspection and found the bores, piston rods, and gland bushings to be in excellent condition, so there was no need to hone/replace the cylinders or replace the most expensive parts.

I stripped and painted the cylinders and a few other bits. Here is one of the cleaned up cylinders, with the original piston rod, piston, gland, and clamps, shown with the new seals and ball joints:

I installed both cylinders and tested them. Here's the left-hand cylinder installed:
No leaks and no play in the steering.
