Your axles are the last link in transferring power from the engine to your wheels. They’re strong parts that last a long time, but they can run into trouble. Of course, axles just wear out over time and need to be replaced, and sometimes axle seals leak, causing the axle to wear out prematurely. Lubricant leaks out and water and dirt can get in and contaminate the gears. When this happens, you might hear strange noises coming from your axle.
