Wheel Stud (Stud Circle) Runout

Use the wheel stud runout procedure whenever the following conditions occur:
- The off-vehicle radial runout differs significantly from the on-vehicle radial runout
- Earlier attempts to correct the tire and wheel vibration condition have been unsuccessful




1. Position the dial indicator in order to contact the wheel mounting studs. Measure the stud runout as close to the flange as possible.
2. Turn the hub to register on each of the studs.
3. Zero the dial indicator on the lowest stud.
4. Rotate the hub again and check the total amount of runout.
