Take off the brakes, knock the stud out with a hammer and punch. To put the new stud on the poor mans way without an installer: you will need a nut larger than the stud and a washer. Put the stud through the hub, put the washer over the stud, put the oversize nut on the stud. Then use your new lug nut and tighten until it is tight, coat all of the surfaces good in oil. Where the washer touches the hub, nut touches the washer, lug nut touches the oversize nut and the threads. Once the back of the stud is flush to the hub you are set. Clean all the oil off of everything with brake clean and re-assemble everything.
