Have you noticed a strange grinding or squealing noise from your wheels? It could be your wheel bearings. Although they're designed to last over 100k miles in most vehicles, contamination from a leaking seal can cause premature breakage. If your wheels are chattering or if you've driven through hub deep water, it's a good idea to bring your vehicle in to have the wheels inspected and, where possible, the grease repacked. A failed wheel bearing can be dangerous, so don't hesitate to schedule an appointment if symptoms are present.
