  • Remove bolt and inspect for damage
  • Check pulley and surrounding components for wear

5. Installation of New Bolt

  • Clean all mating surfaces thoroughly
  • Apply new thread locker if specified by manufacturer
  • Install new bolt (never reuse old bolt)
  • Torque to manufacturer specifications using torque wrench
  • In many cases, additional angle tightening is required

  • Replace any removed covers or shields
  • Reinstall wheel if removed

7. Final Checks

  • Lower vehicle
