How to Identify a Faulty Pressure Bearing?
3 Answers
Methods to identify a faulty pressure bearing: When the car is turning, there will be an obvious sense of sinking and instability, and in severe cases, it may collide with the chassis. To check if the pressure bearing needs replacement, open the hood and observe whether the gap spacing at the suspension positions on both sides has increased. The impact of a damaged pressure bearing cannot be ignored. Minor issues may affect comfort, increase tire noise, and cause the vehicle to pull to one side, while severe cases can lead to suspension damage, resulting in steering system failure and traffic accidents. The lifespan of a pressure bearing is generally between 40,000 to 60,000 kilometers. Apart from the quality of the product itself, driving habits and methods are also crucial factors affecting its lifespan.
When driving, I always pay attention to any unusual sounds from the car. The most common sign of a failing wheel bearing is a humming or roaring noise when turning or accelerating, accompanied by noticeable steering wheel vibration, especially when the car shakes severely at high speeds. After parking, I shake the tire by hand—if there's looseness or excessive play, it usually confirms a bearing issue. Don't ignore these signs; get it checked at a repair shop promptly, as neglect could affect the steering system or even lead to dangerous wheel detachment risks. During routine maintenance, I remind mechanics to inspect bearing conditions, because small problems left unattended become costlier to fix later.
Previously, when my car's wheel bearing failed, the symptoms were straightforward: a low rumbling noise would start as soon as I began driving, getting louder with higher speeds and more pronounced during turns. Later, the steering wheel began to wobble left and right, making highway driving downright terrifying. I parked the car and tried shaking the tire by hand, feeling excessive play or wobble, which confirmed the bearing was worn. Now, I conduct regular checks and head straight to the repair shop at the first sign of unusual noises. Ignoring it could lead to more severe mechanical failures, such as brake failure or a tire coming off, which is absolutely unsafe.
