1. Increased Rolling Resistance: A damaged or worn-out CV joint can cause increased rolling resistance, which means the car requires more energy to move forward. This increased resistance can lead to decreased fuel efficiency.
2. Loss of Power Transmission: A faulty CV joint can also cause power loss from the engine to the wheels. This loss of power can reduce the car's overall efficiency, resulting in poor fuel mileage.
3. Transmission Issues: A damaged CV joint can put strain on the transmission, causing it to work harder than necessary. This can lead to transmission problems that can further reduce fuel efficiency.
4. Excessive Friction: A worn-out CV joint can cause excessive friction between the rotating components, which can lead to increased fuel consumption.
Therefore, if you notice a sudden decrease in fuel mileage, it's essential to have your CV joints inspected by a qualified mechanic to identify any issues and ensure optimal fuel efficiency.
