Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety: Engage the parking brake and wear safety glasses.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle securely.
Place jack stands under the vehicle for added safety.

3. Remove Wheel and Brake Components

Tools Required: Socket set, torque wrench
Remove the lug nuts using a socket wrench.
Take off the wheel and set it aside.
Remove the brake caliper and rotor if necessary for better access to the wheel hub assembly.

4. Inspect and Replace Wheel Bearing

Tools Required: Bearing puller, hammer, seal driver (if applicable)
Remove the hub assembly from the spindle by unbolting it.
Inspect the old bearing for any signs of pitting or roughness.
Use a bearing puller to remove the old bearing.
Clean the hub assembly area and install the new bearing using a seal driver to ensure proper seating.

5. Reassemble Components

Reattach the hub assembly to the spindle and torque the bolts to manufacturer specifications.
Reinstall the brake rotor and caliper.
Put the wheel back on and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle off the jack stands.
Torque the lug nuts to the specified value with a torque wrench.
