Unusual Starter Noise

  1. Verify starter is installed properly. Ensure bolts are tight. Repair as necessary and check system for normal operation. If starter is mounted properly, go to next step.
  2. Connect remote starter switch between starter solenoid terminal "B" (positive battery cable connection) and terminal "S" (Red wire). See Figure . Engage starter motor and verify noise is coming from starter motor. If noise is coming from starter motor, go to next step. If noise is not coming from starter motor, diagnose engine mechanical concern. See appropriate article in ENGINES.
  3. Remove starter motor. See STARTER MOTOR  under REMOVAL & INSTALLATION. Inspect flywheel ring gear for wear or damage. If ring gear is okay, replace starter motor. If ring gear is worn or damaged, replace ring gear and inspect starter drive gear. If drive gear is also damaged, replace starter motor.
