Solution

1. Preparation

Gather tools and parts required for the replacement.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure safety while working.

3. Remove Wheel and Brake Components

Use a lug wrench to remove the wheel by loosening the lug nuts.
Remove the brake caliper by unbolting it and hanging it using a bungee cord to avoid stress on the brake line.
Remove the brake rotor if necessary to access the wheel bearing.

4. Remove the Wheel Bearing

If applicable, remove the dust cap from the wheel hub to expose the bearing.
Use a socket set to remove the hub nut securing the wheel bearing.
Carefully use a bearing puller or slide hammer to remove the wheel bearing from the hub.

5. Install New Wheel Bearing

Clean the hub area and apply a thin layer of grease to the new wheel bearing.
Carefully press or hammer the new wheel bearing into the hub until it is seated properly.
Reinstall the hub nut and tighten to the manufacturer’s specified torque (typically around 150-200 ft-lbs, but verify with specific torque specifications for the Tacoma).

6. Reassemble Components

Reinstall the brake rotor and caliper.
Mount the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern.

7. Final Checks

Reconnect the negative battery terminal.
Conduct a test drive to ensure everything is functioning correctly.
