hey guys so out of nowhere a few weeks ago on my 62 the front u joint housing i think its called a yoke started hitting the floor really aggressively. I haven't driven the car above 5mph because its so aggressive at that speed. just one of the four ends of the yoke is hitting. i checked both u joints, both are good. so i checked the trans mounts by jacking up were the trans pan is no play in that either. im really stumped as to what this is so any help would be awesome.
