What are the symptoms of a warped wheel hub?
2 Answers
The symptoms of a warped wheel hub are: 1. The car pulls to one side; 2. The tire may slip off the wheel hub; 3. The car may lose control. The causes of a warped wheel hub are: 1. Wear and deformation caused by friction between the brake friction pads and the brake drum; 2. Severe wear of the brake drum. The maintenance methods for wheel hubs are: 1. When the vehicle is in a humid area, the wheel hub should be cleaned frequently to prevent salt corrosion on the aluminum surface; 2. If necessary, after cleaning, the wheel hub can be waxed to maintain its luster; 3. When the wheel hub temperature is high, it should be allowed to cool naturally before cleaning. Do not use cold water to clean it, as this can damage the aluminum wheel hub, deform the brake disc, and affect braking performance. Using cleaning agents on the wheel hub can cause chemical reactions on the surface, leading to loss of luster.
Just helped my cousin fix his old Focus and encountered a wheel out-of-round issue. The most obvious symptom was that once the speed hit 60 km/h, the steering wheel shook like a phone on vibrate mode, even the water bottle on the dashboard was dancing. It got even crazier above 80 km/h—the whole cabin buzzed with resonance, and the passenger seat trembled. After parking, I could feel obvious wavy irregular wear patterns by running my hand over the tire tread. Later, when we lifted it on a jack and spun the wheel freely, you could see with the naked eye that the wheel wobbled like an egg doing the twist. If not fixed promptly, the bearings would be toast in no time. My advice: if you notice high-frequency steering wheel vibrations, get to a tire shop for a wheel balance check ASAP.
