Operating Condition - Vehicle is Moving

Depends more on how the vehicle is operated.
- Speed-related
  1. Related to vehicle speed
    - Pitch increases with vehicle speed. Refer to SYMPTOM TROUBLESHOOTING CHART - TIRE NOISE/VIBRATION .
    - Noise occurs at specific vehicle speed. A high-pitch noise (whine). Refer to SYMPTOM TROUBLESHOOTING CHART - DRIVELINE SYSTEM NOISE/VIBRATION .
    - Loudness proportional to vehicle speed. Low-frequency noise at high speeds, noise and loudness increase with speed. Refer to SYMPTOM TROUBLESHOOTING CHART - DRIVELINE SYSTEM NOISE/VIBRATION .
    - A low-pitched noise (drumming). Refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE NOISE/VIBRATION .
    - Vibration occurs at a particular speed (MPH) regardless of acceleration or deceleration. Refer to SYMPTOM TROUBLESHOOTING CHART - TIRE NOISE/VIBRATION .
    - Noise varies with wind/vehicle speed and direction. Refer to SYMPTOM TROUBLESHOOTING CHART - AIR LEAK & WIND NOISE .
  2. Related to engine speed.
    - Noise varies with engine RPM. Refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE NOISE/VIBRATION .
    - Vibration occurs at a particular speed (MPH) regardless of engine speed (RPM).
- Acceleration:
  1. Wide open throttle (WOT).
    - Engine induced contact between components. Inspect and repair as necessary.
    - Noise is continuous throughout WOT. Exhaust system or engine ground out. Refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE NOISE/VIBRATION .
  2. Light/moderate acceleration.
    - Tip-in moan. Engine/exhaust noise. Refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE NOISE/VIBRATION .
    - Knock-type noise. Refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE NOISE/VIBRATION .
    - Driveline shudder. Refer to SYMPTOM TROUBLESHOOTING CHART - DRIVELINE SYSTEM NOISE/VIBRATION .
    - Engine vibration. Refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE NOISE/VIBRATION .
  3. Turning noise. Refer to SYMPTOM TROUBLESHOOTING CHART - STEERING NOISE/VIBRATION .
  4. Braking.
    - Clicking sound is signaling ABS is active. Acceptable ABS sound.
    - A continuous grinding/squeal. Refer to SYMPTOM TROUBLESHOOTING CHART - BRAKE NOISE/VIBRATION .
    - Brake vibration/shudder. Refer to SYMPTOM TROUBLESHOOTING CHART - BRAKE NOISE/VIBRATION .
  5. Clutching.
    - A noise occurring during clutch operation. Refer to SYMPTOM TROUBLESHOOTING CHART - TRANSAXLE (MANUAL) AND POWER TAKE OFF UNIT NOISE/VIBRATION .
    - Vibration. Refer to SYMPTOM TROUBLESHOOTING CHART - TRANSAXLE (MANUAL) AND POWER TAKE OFF UNIT NOISE/VIBRATION .
  6. Shifting.
    - Noise or vibration condition related to the transaxle (automatic). Refer to SYMPTOM TROUBLESHOOTING CHART - TRANSAXLE (AUTOMATIC) NOISE/VIBRATION .
    - Noise or vibration related to the transaxle (manual). Refer to SYMPTOM TROUBLESHOOTING CHART - TRANSAXLE (MANUAL) AND POWER TAKE OFF UNIT NOISE/VIBRATION .
  7. Engaged in four-wheel drive. Refer to SYMPTOM TROUBLESHOOTING CHART - TRANSAXLE (MANUAL) AND POWER TAKE OFF UNIT NOISE/VIBRATION .
  8. Cruising speeds
    - Accelerator pedal vibration. Refer to SYMPTOM TROUBLESHOOTING CHART - ENGINE NOISE/VIBRATION .
    - Driveline vibration. Refer to SYMPTOM TROUBLESHOOTING CHART - DRIVELINE SYSTEM NOISE/VIBRATION .
    - A shimmy or shake. Refer to SYMPTOM TROUBLESHOOTING CHART - TIRE NOISE/VIBRATION .
  9. Driving at low/medium speeds.
    - A wobble or shudder. Refer to SYMPTOM TROUBLESHOOTING CHART - TIRE NOISE/VIBRATION .
- Depends more on where the vehicle is operated.
  1. Bump/pothole, rough road or smooth road. Refer to SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NOISE/VIBRATION .
    - Noise is random or intermittent occurring from road irregularities. Refer to SYMPTOM TROUBLESHOOTING CHART - SQUEAK AND RATTLE .
    - Noise or vibration changes from one road surface to another. Normal sound changes.
    - Noise or vibration associated with a hard/firm ride. Refer to SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NOISE/VIBRATION .
