How to Replace a Drum Stud in the Hub of a 1999 Toyota Corolla
A thread on a drum stud, while installing a lug nut, can become damaged easily by cross-threading. A drum stud with damaged threads won't be able to accept a lug stud used to hold the wheel in place. Rather than forcing the lug nut on the stud, most backyard mechanics can change the single drum stud without replacing the entire wheel hub. The studs can be purchased individually from most auto part stores.
