Yesterday while pulling from a stop and making a left hand turn, right front tire breaks loose coming off rig. Pulled off side of road, collected tire and only found one lug nut with sheared stud in middle of road. No noted driving or handling changes prior except very slight shimmy in steering in gentle turns driving a short distance from ski resort. Tire did damage quarter panel as it broke off but appears to be minimally bent inward. Essentially truck landed on rotor as I pulled off the road, maybe 20 feet or so. Cleaned thing up a bit this morning, all studs sheared essentially the same it appears. No damage noted to hub or other steering components by visual inspection. My question at the moment is, can I remove the hub from the rotor without first removing the drive flange, to replace the studs? Can they come off together?
