• Wheel chocks
• Sockets and wrenches
• Hammer or mallet
• Bearing puller or slide hammer
• New wheel bearings
• New seals

Step-by-Step Instructions

1. Safety First

• Before starting, engage the parking brake and chock the wheels opposite the one you're replacing.
• Use a floor jack to raise the vehicle and secure it with jack stands.

2. Remove the Wheel and Tire

• Use a lug wrench to loosen the lug nuts on the wheel you're replacing.
• Remove the lug nuts and lift the wheel and tire off the hub.

3. Remove the Brake Caliper

• Use a socket wrench to remove the bolts holding the brake caliper in place.
• Carefully lift the caliper off the rotor and tie it out of the way with a zip tie or bungee cord.

4. Remove the Rotor

• Remove the screw holding the rotor in place.
• If the rotor is stuck, use a hammer or mallet to gently tap it loose.

5. Remove the Hub

• Use a socket wrench to remove the bolts holding the hub assembly in place.
• Carefully pull the hub assembly off the axle.

6. Remove the Old Bearing

• Use a bearing puller or slide hammer to remove the old bearing from the hub.
• If the bearing is stuck, use a hammer or mallet to gently tap it out.

7. Clean the Hub

• Use brake cleaner to thoroughly clean the hub surface where the new bearing will be installed.

8. Install the New Bearing

• Apply a thin layer of anti-seize compound to the hub surface.
• Carefully press the new bearing into place using a hammer or mallet.

9. Install the Hub

• Place the hub assembly back onto the axle.
• Tighten the hub bolts to the specified torque.

10. Install the Rotor

• Place the rotor onto the hub.
• Tighten the rotor screw to the specified torque.

11. Install the Brake Caliper

• Place the brake caliper over the rotor.
• Install the caliper bolts and tighten them to the specified torque.

12. Install the Wheel and Tire

• Place the wheel and tire onto the hub.
• Tighten the lug nuts to the specified torque.

13. Lower the Vehicle

• Tighten the lug nuts one last time.

Tips and Tricks

• Use a bearing puller or slide hammer to remove the old bearing. Trying to pry the bearing off with a screwdriver or other tool can damage the hub.
• Be careful not to damage the new bearing when installing it. A small amount of anti-seize compound can help make installation easier.
• Tighten all bolts and nuts to the specified torque. Overtightening can damage the bolts or nuts, while undertightening can lead to loose components.
• Lubricate the new bearing with grease. This will help extend the life of the bearing.

Interesting Stories

1. The Case of the Squeaky Wheel

Once upon a time, there was a car owner who heard a squeaky noise coming from one of the wheels. He ignored the noise for a while, but it got worse and worse. Finally, he took the car to a mechanic, who diagnosed the problem as a bad wheel bearing. The mechanic replaced the bearing, and the squeaky noise went away.

2. The Loose Wheel

Another car owner was driving down the road when one of his wheels suddenly came loose. The car swerved out of control and crashed into a ditch. The driver was lucky to escape with his life. The crash was later determined to have been caused by a failed wheel bearing.

3. The Punctured Tire

A third car owner was driving on a highway when a nail punctured one of his tires. The tire quickly went flat, and the driver had to pull over to the side of the road. As he was changing the flat tire, he noticed that the wheel bearing on that wheel was also damaged. He replaced the bearing, along with the flat tire, and was able to continue on his way.
