Went to learn on a spare steering box I have by taking it apart .I don’t know about taking the part with all of the ball bearings apart but the rest looks not bad .I took one apart a little looked at the one in the truck and it looks like they are not that worn so I put some corn head grease in the one in my truck and will see how it goes if it leaks a bit that is okay. I am curious if anyone has tried to replace the seal as it looks very thin or has anyone replaced any other parts in the box ,what was the experience like .Thanks Kevin
