What are you referring to? The clip that holds the nut in place? If so I once had a factory titanium wheel nut that didn't have any means to insert the clip/pin so what I did was loop some wire through the two spindle holes over and over to stop the nut unwinding... never moved
Allo Allo what have we here then, I cant see anything missing although if you are referring to the safety clip around the nut it's better to secure it with a tiewrap through the two loops to stop it coming off. Steve
