Q: my 63 one ton axle bearing nut is 8 sided as opposed to hex. it is 2 3/4 sae. does anyone know where i can purchase a tool to remove and install this nut. tia. try a real auto parts store not one of the national chains but a locally owned store. also if you have a farm/tractor supply store in your area many have tools like this for heavy equipment. greg .
