Introduction

This tutorial will guide you through the process of replacing a wheel bearing hub assembly in your car, a task that can save you time and money. Following these steps will help you diagnose and replace a worn or noisy wheel bearing, ensuring your vehicle runs smoothly again.

Step 1: Diagnose the Wheel Bearing Issue

• Listen for unusual noises while driving, such as humming or grinding sounds.
• Check for excessive play by grabbing the wheel and shaking it; any noticeable movement indicates a worn bearing.
• Inspect the tire for uneven wear, such as scalloped ridges, which is a sign of a failing bearing.

Step 2: Gather Necessary Tools and Materials

To complete the replacement, you will need:

• Bit socket set (especially a T50)
• Wrench set
• Mechanic’s tool set
• Steel jack and jack stands
• Shop towels
• Flashlight
• Disposable gloves

Step 3: Remove the Wheel

1. Use the steel jack to lift the car.
2. Secure the car with jack stands.
3. Remove the lug nuts and take off the wheel.

Step 4: Remove the Brake Components

1. Remove the Brake Caliper
   • Use a socket with an allen wrench head.
   • Unscrew the caliper bolts and slide the caliper off to the side.
2. Remove the Caliper Mounting Bracket
   • Locate and remove the two bolts holding the bracket in place.
   • Take off the bracket and set it aside.
3. Remove the Brake Rotor
   • If the rotor is stuck, tap it lightly with a hammer to loosen it.

Step 5: Remove the Old Hub Assembly

1. Locate the four bolts securing the hub assembly.
2. Use a ratchet with an extension to reach and remove these bolts.
3. If the shock absorber is in the way, unbolt it to gain access to the last two bolts.
4. Carefully pull the hub assembly off.

Step 6: Transfer the ABS Sensor

• Unscrew the ABS sensor from the old hub assembly.
• Install the ABS sensor onto the new hub assembly by screwing it in place.

Step 7: Install the New Hub Assembly

1. Align the new hub assembly and slide it into place.
2. Insert the bolts and snug them up.
3. Don’t forget to connect the ABS sensor if applicable.

Step 8: Reassemble the Brake Components

1. Reinstall the shock absorber and secure it with bolts.
2. Slide the brake rotor back onto the hub.
3. Reattach the caliper bracket and secure it with bolts.
4. Slide the caliper back on and tighten the bolts.

Step 9: Reattach the Wheel

• Place the wheel back onto the hub.
• Hand-tighten the lug nuts and then lower the car.
• Tighten the lug nuts fully with a wrench.
