5 Ways to Fix a Noisy 2008 Chevy Impala Front Wheel Bearing

This article cuts to the chase. If your 2008 Chevy Impala’s front wheel bearing is making noise, you’re likely facing replacement. We’ll cover how to diagnose the problem, assess the urgency, and walk through some critical steps in deciding whether to DIY or seek professional help. We also dive into choosing the right replacement part, including some pitfalls to avoid.

A failing front wheel bearing on your 2008 Chevy Impala usually announces itself with a distinct noise. This noise often changes with speed, becoming louder or more pronounced as you accelerate. It’s frequently described as a humming, rumbling, or grinding sound. But here’s the catch: other issues can mimic these symptoms.

• Differentiating from Tire Noise: Tire noise, especially from worn or unevenly worn tires, can sound remarkably similar. A simple test: rotate your tires (if feasible). If the noise changes or disappears, the tires are likely the culprit.

  

• Checking for Play: Jack up the suspected wheel and try to wiggle it. Grasp the tire at the 12 o’clock and 6 o’clock positions and push/pull. Then do the same at the 3 o’clock and 9 o’clock positions. Excessive play (more than a slight wobble) indicates a worn bearing.

• Listen Closely: While spinning the wheel (with the car safely supported on jack stands), listen closely for any roughness or grinding coming from the hub area. A stethoscope can be helpful for pinpointing the source.

• Don’t Ignore ABS Light: Sometimes, a failing wheel bearing can damage the ABS sensor. If your ABS light is illuminated alongside the noise, the bearing is a strong suspect. See more about Anti-lock Braking System at Wikipedia.

How urgently do you need to address that noisy 2008 Chevy Impala front wheel bearing? The answer depends on the severity of the wear and the potential consequences.

• Minor Noise, Minimal Play: If the noise is faint and there’s only very slight play in the wheel, you likely have some time. However, don’t delay indefinitely. The bearing will continue to degrade.

• Loud Noise, Noticeable Play: This is a more pressing issue. Continued driving could lead to bearing failure, potentially causing the wheel to lock up while driving.

• ABS Light Illuminated: Address this immediately. A damaged ABS sensor compromises your car’s braking system, impacting safety, it is very important for you.

• Long Trips: Never embark on a long road trip with a suspected bad wheel bearing. The risk of failure far outweighs the convenience.

Replacing a front wheel bearing on a 2008 Chevy Impala isn’t a job for the faint of heart. It requires specialized tools and a good understanding of automotive mechanics.

• DIY Considerations:

  • Tools: You’ll need a wheel bearing press (or access to one), a torque wrench, sockets, wrenches, penetrating oil, and potentially a slide hammer. Renting a bearing press is an option, but ensure it comes with the correct adapters for your Impala.
  • Experience: If you’ve never tackled a similar repair, this isn’t the best place to start. Improper installation can quickly ruin a new bearing.
  • Time: Expect to spend several hours on this job, even with experience.
  • Safety: Working under a car always carries risk. Use jack stands and follow proper safety procedures.

• Professional Installation:

  • Cost: Expect to pay for parts and labor. Call around for quotes, as prices can vary.
  • Warranty: A reputable shop will warranty their work and the parts they install.
  • Convenience: Someone else does the dirty work!

Personal Insight: I’ve tackled wheel bearing replacements myself, and while rewarding, it’s not always cost-effective considering the time and potential for error. If I’m even slightly unsure, I prefer to let a professional handle it. The key is to find a mechanic you trust. Get recommendations from friends and family.

Not all wheel bearings are created equal. Choosing the right replacement for your 2008 Chevy Impala is crucial for longevity and performance.

• OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) bearings are made by the same manufacturer who supplied the parts to Chevrolet. Aftermarket bearings are made by other companies. OEM bearings tend to be more expensive but often offer superior quality and durability. Aftermarket bearings can be a good option if you choose a reputable brand.

• Bearing Assembly: For the 2008 Impala, you’ll likely be purchasing a complete hub assembly, which includes the bearing, hub, and sometimes even the ABS sensor. This simplifies the installation process.

• Brand Reputation: Stick with well-known brands like Timken, SKF, or Moog. Read online reviews before purchasing.

• Check the ABS Sensor: If your ABS light was illuminated, consider replacing the ABS sensor along with the wheel bearing, even if the new hub assembly includes one. Sometimes, aftermarket sensors can be problematic.

• Beware of RockAuto Specials: While RockAuto often has great prices, I’ve learned from experience that their ultra-budget, no-name bearings can be a gamble. I once installed a bearing from them that failed within a year. It’s worth spending a bit more for a quality part.

• Grease Packing: Some bearings come pre-greased, while others require you to pack them with grease before installation. Always follow the manufacturer’s instructions.

• Proper Torque: Use a calibrated torque wrench to tighten the hub assembly bolts to the manufacturer’s specifications. Under- or over-tightening can damage the bearing.

This is not a complete replacement guide. Refer to a detailed repair manual or online video for specific instructions for your 2008 Chevy Impala. This is to provide a general overview.

1. Loosen Lug Nuts: Before jacking up the car, loosen the lug nuts on the wheel.

2. Raise and Secure: Safely raise the vehicle with a jack and secure it with jack stands.

3. Remove Wheel: Remove the wheel.

4. Disconnect ABS Sensor: Disconnect the ABS sensor wiring (if equipped).

5. Remove Brake Caliper and Rotor: Remove the brake caliper and rotor. Support the caliper so it’s not hanging by the brake line.

6. Remove Hub Assembly: This is often the trickiest part. You may need to use a slide hammer or penetrating oil to loosen the hub assembly from the spindle. Unbolt the hub assembly from the steering knuckle.

7. Install New Hub Assembly: Install the new hub assembly, ensuring it’s properly seated.

8. Reassemble: Reinstall the brake rotor, caliper, ABS sensor (if removed), and wheel.

9. Torque to Spec: Torque the hub assembly bolts and lug nuts to the manufacturer’s specifications.

10. Test Drive: Lower the vehicle and take it for a test drive. Listen for any unusual noises.

Practical Advice: Always use new hub bolts. They are often torque-to-yield and should not be reused.

Table: Common Tools for 2008 Chevy Impala Front Wheel Bearing Replacement

Once you’ve replaced the front wheel bearing on your 2008 Chevy Impala, there are a few things you can do to help prolong its life:

• Avoid Potholes: Hitting potholes and other road hazards can damage wheel bearings.

• Proper Tire Inflation: Maintain proper tire inflation to reduce stress on the bearings.

• Wheel Alignment: Ensure your wheels are properly aligned. Misalignment can cause uneven wear on the bearings.

• Regular Inspections: Have your wheel bearings inspected periodically, especially if you notice any unusual noises or vibrations.

By following these tips, you can help keep your 2008 Chevy Impala rolling smoothly for years to come. Remember, safety is paramount, so don’t hesitate to seek professional help if you’re uncomfortable with any aspect of the repair.
