Wheel stud spinning

7 1/4” ? Pull the access cover, remove the cross pin, push the axle in and pull the c clip and slide the axle, drum, and wheel out. There should be enough clearance between the drum and backing plate to allow the c clip to come off. Yes you may need to loosen the brake shoes and replace a seal and gear oil, but you’ll have all the access to the backside of the stud and won’t mess up the rim.
