Just put new tires on Spyder, had to remove hitch, reinstalling hitch but can't find torque spec for this bolt. Maybe good and snug with castle nut aligned with hole in axle and new cotter pin?
If you're talking about the hitch bolt and not the axle nut then yes, just snug it up good and pin it. Don't overtighten it and don't leave it loose either.
If you just want to torque it then 15-20 ft lbs will work.
