If you're experiencing a humming, rumbling, or grinding noise coming from your 2012 Chevy Malibu, it's likely a sign of a failing hub bearing. This critical component plays a crucial role in supporting the weight of your vehicle and allowing the wheels to turn smoothly.
Regular Inspection: Inspect your hub bearings regularly for any signs of wear or damage. This includes checking for any unusual noises, vibrations, or wobble in the wheels.
Proper Lubrication: Ensure your hub bearings are adequately lubricated to minimize friction and prevent premature wear. Refer to your vehicle's manual for the recommended lubrication schedule.
Avoid Impact: Avoid driving over potholes, curbs, or other road hazards that could impact your hub bearings. These impacts can cause damage or misalignment.
Replacement: If your hub bearing requires replacement, it's recommended to visit a qualified mechanic for professional installation. The labor cost for hub bearing replacement typically ranges from $200 to $300 per wheel.
Materials: The cost of new hub bearings varies depending on the brand and quality. Typically, they range from $100 to $250 per wheel.
Labor Cost | Materials Cost |
---|---|
$200 - $300 | $100 - $250 |
Ignoring Warning Signs: Neglecting unusual noises or vibrations can lead to more severe damage and costly repairs.
DIY Replacements: Hub bearing replacement requires specialized tools and expertise. Attempting DIY replacements may result in improper installation and safety hazards.
Using Substandard Parts: Opting for cheap or non-genuine hub bearings can compromise performance and durability.
