Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the vehicle’s battery if working on electrical components.

2. Lift the Vehicle

Use a jack to raise the vehicle safely.
Place jack stands under the vehicle to secure it.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Carefully remove the wheel from the hub.

4. Remove the Brake Components

Take off the brake caliper by removing the caliper bolts. Use a torque wrench to ensure proper reinstallation.
Suspend the caliper using a bungee cord to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws and sliding it off.

5. Inspect and Replace Wheel Bearings

Remove the bearing assembly from the hub by taking out the retaining clips and bolts.
Inspect the bearings for wear, pitting, or damage. If they are damaged, proceed with replacement.
Clean the hub area and apply new grease to the new bearing before installation.
Install the new wheel bearing assembly and secure it with retaining bolts.

6. Reassemble Components

Reinstall the brake rotor and caliper, tightening bolts to manufacturer specifications.
Put the wheel back on and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and remove the jack stands.
Tighten the lug nuts in a star pattern to the specified torque.
