Wheel Stud / Lug Nut: Service and Repair

REMOVAL

CAUTION: If a wheel mounting stud needs to be replaced in the hub and bearing assembly, the studs CANNOT be hammered out of the hub flange. If a stud is removed by hammering it out of the bearing flange, damage to the hub and bearing assembly will occur leading to premature bearing failure.

1. Raise vehicle on jackstands or centered on a frame contact type hoist. See Hoisting in the Lubrication and Maintenance section of this manual for the required lifting procedure to be used for this vehicle.
2. Remove the front wheel and tire assembly from the vehicle.






3. Remove the disc brake caliper assembly from the steering knuckle. Refer to the Disc Brake System for the removal procedure.






4. Remove brake rotor from hub, by pulling it straight off wheel mounting studs.
