Solution

1. Preparation

Gather all tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Remove the Wheel

Loosen the lug nuts using a lug wrench.
Raise the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Components

Remove the brake caliper by unbolting it from the bracket (use a socket set).
Suspend the caliper using a bungee cord to avoid stress on the brake line.
Remove the brake rotor by unscrewing the retaining screws or sliding it off.

4. Remove the Old Wheel Bearing

Remove any dust cover or retaining ring if applicable.
Unbolt the wheel bearing assembly from the hub using a socket set.
Carefully extract the wheel bearing from the hub using a bearing puller if necessary.

5. Install the New Wheel Bearing

Clean the hub area where the new bearing will be installed.
Press the new wheel bearing into the hub using a bearing press. Ensure it is seated correctly.
Reattach the wheel bearing assembly to the hub, securing it with the appropriate torque specifications (usually 50-80 ft-lbs, check manufacturer specs).

6. Reassemble the Brake Components

Reinstall the brake rotor and secure it with retaining screws.
Reattach the brake caliper and tighten the bolts to the specified torque (usually around 25-35 ft-lbs).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (usually 80-100 ft-lbs).
