Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, mechanic’s stethoscope, wheel bearing puller, grease.
Safely lift and secure the vehicle with jack stands.
Ensure the vehicle is in park (or neutral for manual) and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts while the wheel is still on the ground.
Lift the vehicle and remove the lug nuts completely.
Take off the wheel and set aside.

3. Inspect and Remove Brake Components

Remove the brake caliper by unbolting the caliper bracket and hanging it with a bungee cord (do not let it dangle by the brake line).
Remove the brake rotor, if necessary, to gain access to the wheel bearing.

4. Remove Wheel Bearing

Remove the dust cover, if applicable, to expose the wheel bearing.
If the bearing is pressed into the hub, use a wheel bearing puller to extract it. Follow manufacturer specifications for any special tools or methods needed.
Clean the hub surface before installing a new bearing.

5. Install New Wheel Bearing

Press the new wheel bearing into place, ensuring it is seated correctly.
Reinstall the dust cover if applicable.

6. Reassemble Brake Components

Reinstall the brake rotor and caliper, ensuring all bolts are torqued to manufacturer specifications.
Reattach the wheel and tighten the lug nuts in a star pattern to the specified torque.

7. Lower Vehicle and Test

Carefully lower the vehicle from the jack stands.
Conduct a road test to ensure the issue has been resolved and listen for any abnormal noises.
