Understanding Wheel Bearings and Their Importance
Wheel bearings are essential components that allow your wheels to rotate smoothly and efficiently.

- Noise: A rumbling, grinding, or roaring sound, especially when turning or driving at higher speeds.
- Vibration: A noticeable vibration or shaking in the steering wheel or through the car.
- Roughness: A feeling of unevenness or roughness when driving.
- Play in the wheel: Excessive movement or looseness in the wheel when you try to move it side to side.
If you experience any of these symptoms, it’s crucial to address the issue promptly to prevent further damage to your car. Replacing worn-out wheel bearings is essential for maintaining safe and comfortable driving.

Step-by-Step Guide to Replacing Wheel Bearings on Your Acura TL
1. Preparation:
- Safety First: Park your Acura TL on a level surface and engage the parking brake. Chock the rear wheels to prevent the car from rolling.
- Loosen Lug Nuts: Use the lug wrench to loosen the lug nuts on the affected wheel. Don’t remove them completely yet.
- Jack Up the Car: Place the jack under the designated jacking point for your Acura TL and raise the car until the affected wheel is off the ground. Secure the car using jack stands for safety.
2. Removing the Wheel:
- Remove Lug Nuts: Remove the lug nuts completely and take off the wheel.
3. Removing the Brake Caliper and Rotor:
- Loosen Caliper Bolts: Locate the bolts holding the brake caliper to the bracket. Use a socket wrench to loosen these bolts, but don’t remove them completely yet.
- Hang the Caliper: Using a wire or rope, hang the brake caliper to the suspension. This prevents stress on the brake hose.
- Remove Rotor: Remove the bolts holding the rotor to the hub. The rotor should now come off.
4. Removing the Wheel Bearing Assembly:
- Remove Hub Nut: Use a breaker bar and socket to remove the hub nut from the center of the rotor. This can be very tight, so you might need to use a pipe extension on the breaker bar for leverage.
- Remove the Old Bearing: Use a pry bar to gently separate the wheel bearing assembly from the hub. You may need to tap on the assembly with a hammer to break it free.
5. Installing the New Wheel Bearing:
- Clean the Hub: Thoroughly clean the hub and the new bearing assembly using a wire brush or a rag.
- Grease the New Bearing: Pack the new wheel bearing with grease. This will help ensure smooth operation and prevent premature wear.
- Install the New Bearing: Place the new wheel bearing assembly onto the hub. Ensure it’s seated properly and aligned.
- Install the Hub Nut: Tighten the hub nut to the specified torque, which you can find in your Acura TL’s owner’s manual or online.
6. Reassembly:
- Reinstall the Rotor: Place the rotor back onto the hub and tighten the bolts.
- Reinstall the Caliper: Remove the wire or rope holding the caliper and reattach it to the bracket. Tighten the bolts to the specified torque.
- Lower the Car: Lower the car using the jack and remove the jack stands.
- Tighten Lug Nuts: Tighten the lug nuts to the specified torque.
7. Test Drive:
- Road Test: Take your Acura TL for a test drive to ensure the new wheel bearing is working properly. Listen for any unusual noises or vibrations.
