Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use a jack to lift the front or rear of the Tacoma as needed.
Secure the vehicle with jack stands to prevent it from falling.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel and set it aside.

4. Access the Wheel Bearing

Remove the brake caliper by unbolting it and securing it with a bungee cord to avoid straining the brake line.
Take off the brake rotor by removing the retaining screws or clips if applicable.
If necessary, remove the axle nut using a socket and breaker bar to access the wheel bearing.

5. Replace the Wheel Bearing

Remove the wheel bearing assembly from the hub using a bearing puller if necessary.
Clean the mounting surface and replace the old bearing with a new one, ensuring proper alignment.
Reassemble the components in reverse order, ensuring to torque the axle nut to the manufacturer’s specifications.

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the specified torque.

7. Final Checks

Reconnect the negative battery terminal.
Conduct a test drive to ensure the issue is resolved.
