not too easy to open these steering boxes, is it! it took me a few days, Stretch's classic photo thread, and getting my workbench quite oily before i had it apart. a couple of ball bearings, and the worm gear, looked bad. looking back, i must have gotten it in the jammed state, wondered why tightening it wasn't working, and overtightened. not sure that normal use could ever cause this. anyway, lesson learned -- installing that thing without a helper sucked! but it drives great again now.
