Can You Still Drive with a Bad Rear Wheel Bearing?

[Elsa]

You can drive short distances, but it is recommended to replace it immediately. At best, it will affect comfort, increase tire noise, and cause the vehicle to pull to one side. At worst, it can damage the suspension, leading to steering system failure and potential accidents. Moreover, prolonged high-speed driving can cause excessive heat buildup, resulting in unnecessary wear on other components. Below is an introduction to issues with a bad rear wheel bearing: 1. Issue One: Damage and Rust. If foreign objects enter or the rolling elements become misaligned, it can cause damage, leading to poor impact resistance and abnormal noises. Exposure to acidic liquids or moisture over time can cause rust. 2. Clearance Issues: All automotive components and parts require proper clearance. If the gap between the rolling elements and the raceway is too small, it can lead to friction, heat buildup, and bearing seizure (where the components bond together due to high temperatures). Misaligned or tilted rolling elements will naturally stop functioning. 3. Poor Lubrication: Normally, the lubrication points of rolling bearings should use the highest-quality grease, and the gaps between the inner and outer rings, the cage, and the rolling elements should be fully filled. If this is not done, over time, the lack of grease between the rolling elements and the raceway will result in dry friction, leading to abnormal noises.
