How to Determine if the Front Wheel Bearing is Bad?
2 Answers
To determine if the front wheel bearing is bad, observe the noise emitted by the vehicle while driving; a humming sound indicates a faulty bearing. The reasons for a bad front wheel bearing include: 1. Improper bearing assembly and adjustment; 2. Poor lubrication; 3. Quality issues with the bearing itself. The solution for a bad front wheel bearing is to replace it with a new one. The steps for replacement are as follows: 1. Remove the tire to expose the brake disc and caliper, then locate the front wheel bearing; 2. Remove the dust cover on the bearing to access the large nut securing the bearing, then remove the nut; 3. Remove the bolts securing the brake caliper and take off the caliper; 4. Remove the brake disc, then take off the outer securing nut of the bearing. Pull outward to remove the old bearing, install the new bearing, replace the securing nut, and tighten it.
Having driven for over a decade, I've gained some insights into identifying front wheel bearing failures. After starting the vehicle, listen carefully for any continuous humming or whirring sounds from the front wheel area - if the noise intensifies with speed, be alert. The sound changes noticeably during turns; for example, when turning left, abnormal noise from the right front wheel may suddenly become louder. If the steering wheel starts vibrating inexplicably while driving, especially at speeds between 60-80 km/h, consider bearing issues after ruling out tire problems. You'll also feel increased vibration from the car body, similar to the sensation of an out-of-round wheel. The most direct method is to safely pull over and touch the wheel hub area with your fingers - abnormal heat indicates definite bearing wear. Whenever I encounter this situation, I promptly visit a repair shop to lift the car and check the wheel's looseness.
