I haven't done this in awhile, & am having problems getting the old u joint out of the yoke on my Howse brush hog driveshaft. The old ring-type PTO end froze up & had to be destroyed to get it off. While I'm replacing the front yoke, I might as well replace the u joint. How does it come outa there?? I have pulled the circlips & pounded out the universal to a point it feels solid & won't move anymore, but it isn't clear of the other side of the yoke.
