ABS Issues: In some cases, a faulty wheel bearing can interfere with the anti-lock braking system (ABS), causing the ABS light to illuminate.
Ignoring a failing wheel bearing can lead to significant consequences beyond just annoying noises.
Escalating Damage and Repair Costs
A worn wheel bearing puts additional stress on surrounding components, such as the hub, axle, and even the brakes. Ignoring the issue can lead to a cascade of problems, resulting in more extensive and costly repairs. For example, a severely damaged bearing can cause the wheel to seize up, potentially leading to a dangerous loss of control, especially at highway speeds.
Safety Concerns and Potential Accidents
A failing wheel bearing compromises the vehicle’s handling and stability. The excessive play in the wheel can make it difficult to steer accurately, increasing the risk of accidents, especially in emergency situations. Furthermore, if the bearing fails catastrophically, the wheel could potentially detach from the vehicle, resulting in a serious collision.
My Personal Experience with 2013 Chevy Malibu Wheel Bearings
I once had a 2013 Chevy Malibu where I ignored a subtle humming noise for far too long. The sound started as a faint background hum on the highway and gradually worsened into a noticeable roar. Being a college student at the time, I wrongly chalked it up to road noise and neglected to address the issue. Eventually, the vibration became unbearable, and the repair bill was significantly higher than it would have been if I had addressed it sooner.
Replacing a rear wheel bearing on a 2013 Chevy Malibu is a task that can be tackled by experienced DIYers with the right tools and a good understanding of automotive mechanics. However, it’s not a job for beginners.
