You can add the ball bearing upgrade to the steering box, but I'm not really sure it helps--I've done 3 or 4.
The Cam follower in the steering box--that's a burr under my saddle the way I see a lot of guys "think" they can repair it. You can't take a grade 8 bolt and grind it down adequately on a pedestal grinder and call it a "repair" unless you are fixing a trailer queen that will never drive very much from now until the end of time. Those cam followers are extremely hard. I have taken ones that are only slightly worn to work and set them up on a surface grinder. Real bad ones I've replaced. Pretty sure they are only case hardened, so you don't want to remove too much.
