1. Power Steering Fluid: Check the power steering fluid level and condition. If the fluid is low or dirty, it could cause a whining noise when turning the steering wheel.
2. Power Steering Pump: If the power steering pump is malfunctioning or has low fluid pressure, it may produce a whining sound.
3. Serpentine Belt: Ensure the serpentine belt is properly tensioned and not worn out. A loose or damaged belt can produce a whining noise when in operation.
4. Alternator: A failing or faulty alternator might result in a whining noise due to issues with power generation.
5. Transmission: In certain cases, transmission-related issues such as low transmission fluid or failing bearings can lead to a whining sound.
6. Wheel Bearing: A worn-out or damaged wheel bearing might exhibit a whining noise when driving at specific speeds.
7. Differential: Issues within the differential of your Jeep Commander, such as low differential fluid or worn internal components, could also cause a whining sound.
To accurately identify the source of the whining noise, it's advisable to have your vehicle inspected by a certified mechanic who can properly diagnose and address the issue.
