I am working on my john deere 7220 tractor 3 point ram. Both the top and bottom of the ram has a heim joint with a large (maybe 1-1/4") the end of the pin has a female m10 thread in it. To me it looks like their must be a puller that threads into the pin and pulls the pin out. I am familiar with a slide hammer and thread attachement but is their a better tool for this application. Thanks to all the great garge journal members
