Effect of Bad Wheel Bearings on Gas Mileage (MPG)

Bad wheel bearings can effectively reduce the efficiency of your drivetran. A bad wheel bearing increases the friction in your vehicle and causes the engine to work harder to move your vehicle. Power is lost through the heat and sound created by this increase in friction. Replacing your wheel bearings with a high quality unit will ensure you maintain the best MPG for your vehicle and are not loosing power before it reaches the wheels.
