Just noticed that my 3000 has a lot of play in the left drag link. After a closer look, the nut is really loose. I don't know if this is a typical setup, but mine has a lockwasher and a lock nut. I tried for about an hour or so today to loosen or tighten it with no luck. Is there a secret to keep the ball end from turning. I tried tapping from the top hoping to seat it down in the taper, but still turns. I soaked it in PB and cut a screwdriver slot in the male threaded end. But I still cannot hold it with a large screwdriver while turning the nut. Any suggestions?
