I was hoping someone could help me out, Im gonna go out and buy a grease gun so I can add some much needed grease in my control arms/a-arms but i don't know what size coupler or fitting I need for the little valves or what ever they're called that you plug the grease gun into. If anyone knows for sure what size the valves are or what size coupler/fitting I need for the grease gun I'd really appreciate it. If possible the sooner the better cause I only have a 2 hour window to go pick up the grease gun and go ride and I was hoping to get in at least an hour of ride time. Thanks guys !
