How to Tell if a Thrust Bearing is Faulty?
2 Answers
The methods to determine if a thrust bearing is faulty are: 1. A clicking sound when turning the steering wheel or a creaking noise when rotating the steering wheel while stationary or at low speeds; 2. A clicking sound when making sharp turns at low speeds, accompanied by steering wheel vibration or increased steering effort; 3. Noticeably increased tire noise during driving; 4. Abnormal noises when passing over speed bumps; 5. The vehicle pulling to one side; 6. Damage to the steering system or suspension system. The thrust bearing, also known as the pressure bearing, specifically refers to the thrust bearing of the shock absorber, commonly found in MacPherson strut suspension systems. The thrust bearing is located at the top of the shock absorber, between the spring and the shock absorber top mount, bearing vertical pressure while allowing free rotation.
When driving, if I hear squeaky metal sounds or roaring noises while turning, I know the wheel bearing might be damaged. These sounds are usually more noticeable during slow turns or on bumpy roads because increased friction occurs when it's worn out. The steering wheel may also vibrate slightly, as if the wheel is loose, making it uncomfortable to hold. In severe cases, steering can become stiff and laborious, with an unsmooth turning sensation. You might also notice uneven tire wear on one side because the unbalanced wheel caused by a faulty bearing wears faster. I recommend paying attention to these warning signs and getting your car checked at a repair shop promptly—don’t wait until safety becomes an issue. With over 20 years of driving experience, I’ve seen many accidents caused by bearing failures. Early detection can save you a lot of trouble.
