Common symptoms include humming or grinding noises that increase with speed, wheel vibration, uneven tire wear, ABS warning lights, and steering wheel play.
Modern sealed wheel bearings generally last 150,000-250,000 km under normal driving conditions, but lifespan can be reduced by poor road conditions, impacts, or improper installation.
Most contemporary wheel bearings are sealed, non-serviceable units that require complete replacement when worn or damaged. Attempting to repair sealed bearings compromises lubrication integrity and safety.
