Hi All I fitted a set of 18" Vella wheel I had painted gloss black to my red XF Sportbrake today, they look great but on the last wheel I overtightened a stud and snapped it off! The question is how hard is it to fit a new one? I know it would be calliper and disc off but will I need to take the hub off? It's the rear not the front. Any help would be appreciated. Thanks PS I hope to post a few pics soon of the car and the new wheels plus the additiona stud! When fixed...
