Lots of talk about people fighting with the upper ball joints during install. Some have even not bothered with them and put Howe brand in or others. I put a wire wheel to the threads and they went in very easily. After all was said and done I checked to see how short I could get the rear leg on it, 7 1/8 so I have all the adjustment I need available.
