How to Replace Rear Wheel Bearing BF Falcon: Essential Tips and Tricks

The BF Falcon, a legendary Australian muscle car, is known for its robust performance and enduring reliability. However, even the most dependable vehicles require maintenance, and replacing rear wheel bearings is a common task that every BF Falcon owner might encounter. This comprehensive guide will walk you through the process of replacing rear wheel bearings on your BF Falcon, empowering you to tackle this job with confidence.

Understanding the Importance of Rear Wheel Bearings

Rear wheel bearings are crucial components that support the weight of your vehicle and enable smooth wheel rotation. They consist of a set of steel balls housed within a raceway, allowing the wheel to spin freely while minimizing friction. Over time, these bearings can wear down due to factors like age, mileage, and harsh driving conditions.

Recognizing the Signs of a Worn Rear Wheel Bearing

Identifying a worn rear wheel bearing early on is essential to prevent further damage and ensure your safety. Here are some common signs to watch out for:

• Grinding or growling noise: This is often the most noticeable symptom of a worn bearing, particularly when turning or driving over bumps.
• Wobbly wheel: If you feel a vibration or shaking in the steering wheel, especially at higher speeds, it could indicate a damaged bearing.
• Clicking or popping sound: A clicking or popping sound when turning or braking might be a sign of a broken or damaged bearing.
• Unusual tire wear: Uneven tire wear can be a symptom of a worn bearing, as it can affect the wheel’s alignment.

Gathering the Necessary Tools and Parts

Before embarking on the replacement process, ensure you have all the necessary tools and parts:

• Jack and jack stands: To safely lift the vehicle.
• Lug wrench: To remove the wheel.
• Torque wrench: To ensure proper tightening of bolts.
• Hammer: To tap the bearing raceway.
• Bearing raceway puller: To remove the old bearing raceway.
• Bearing press: To install the new bearing raceway.
• New rear wheel bearing: Ensure you purchase the correct bearing for your BF Falcon model.
• Grease: To lubricate the new bearing.
• Safety glasses and gloves: To protect your eyes and hands.

Step-by-Step Guide to Replacing Rear Wheel Bearings

Now, let’s dive into the step-by-step process of replacing your BF Falcon‘s rear wheel bearings:

1. Prepare the vehicle: Park your BF Falcon on a level surface and engage the parking brake. Chock the front wheels to prevent the vehicle from rolling.

2. Raise the vehicle: Use the jack to lift the rear of the vehicle. Place jack stands securely under the frame, ensuring they are properly positioned.

3. Remove the wheel: Use the lug wrench to loosen the lug nuts. Once loose, remove the wheel and set it aside.

4. Remove the brake caliper: Carefully remove the brake caliper assembly. You may need to use a brake caliper tool to compress the piston. Hang the caliper assembly from the suspension using a wire or rope to prevent stress on the brake hose.

5. Remove the rotor: Remove the rotor from the hub. The rotor may be held in place by a single bolt.

6. Remove the old bearing: Using the bearing raceway puller, carefully remove the old bearing raceway from the hub.

7. Clean the hub: Thoroughly clean the hub and surrounding area to remove any dirt, debris, or old grease.

8. Install the new bearing: Use the bearing press to install the new bearing raceway onto the hub. Ensure a snug fit and avoid damaging the bearing.

9. Lubricate the bearing: Apply a generous amount of grease to the new bearing to ensure smooth operation and prevent premature wear.

10. Reassemble the hub: Reinstall the rotor, brake caliper, and wheel. Tighten the lug nuts to the manufacturer’s specifications using the torque wrench.

11. Lower the vehicle: Remove the jack stands and lower the vehicle to the ground.

12. Test drive: Take your BF Falcon for a test drive to ensure the new bearing is properly installed and functioning correctly. Listen for any unusual noises or vibrations.

Post-Replacement Maintenance Tips

After replacing your rear wheel bearings, follow these tips to maintain their longevity:

• Regular lubrication: Periodically lubricate the bearings with grease to prevent wear and tear.
• Proper tire pressure: Maintain the correct tire pressure to reduce stress on the bearings.
• Avoid overloading: Avoid overloading your vehicle, as it puts extra strain on the bearings.
• Inspect for damage: Regularly inspect the bearings for any signs of damage or wear.

A Final Word on Replacing Rear Wheel Bearings on Your BF Falcon

Replacing rear wheel bearings on your BF Falcon might seem daunting, but with the right tools, guidance, and a bit of patience, it’s a manageable task. By following the steps outlined in this guide, you can ensure your BF Falcon continues to deliver its renowned performance and reliability for years to come.

Answers to Your Most Common Questions

Q1: How often should I replace my BF Falcon‘s rear wheel bearings?

A1: The lifespan of wheel bearings varies depending on driving conditions and maintenance practices. However, a general guideline is to replace them every 50,000 to 100,000 miles.

Q2: Can I use a hammer to install the new bearing raceway?

A2: While a hammer might seem tempting, it’s not recommended for installing a bearing raceway. Using a hammer can damage the bearing and lead to premature failure. A bearing press is the safest and most effective tool for this task.

Q3: Why is it important to use the correct grease for the bearing?

A3: Using the appropriate grease ensures proper lubrication and protects the bearing from wear and tear. The wrong grease can lead to premature bearing failure.

Q4: What should I do if I hear a grinding noise after replacing the bearing?

A4: If you hear a grinding noise after replacing the bearing, it could indicate that the bearing was not installed correctly, or it might be a sign of another problem. It’s best to re-inspect the installation and consult a mechanic if needed.
