Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, wheel chocks.
Ensure the vehicle is parked on a level surface and the engine is off.
Apply the parking brake.

2. Remove Wheel

Loosen the lug nuts while the vehicle is still on the ground.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Tools Required: Socket set.
Remove the brake caliper by unscrewing the mounting bolts. Secure the caliper to the suspension using wire or a bungee cord, ensuring it doesn't hang by the brake line.
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

4. Remove Hub Assembly

Tools Required: Torque wrench, socket set.
Remove any retaining clips and bolts securing the hub assembly.
Carefully slide the hub assembly off the spindle. You may need to tap it gently with a hammer if it’s stuck.

5. Inspect and Replace Wheel Bearings

Tools Required: Bearing puller, grease, new wheel bearings.
Use a bearing puller to remove the old wheel bearings from the hub.
Clean the hub and apply fresh grease to the new wheel bearings before installing them.
Press or tap the new bearings into place, ensuring they are seated properly.

6. Reassemble Components

Reinstall the hub assembly and secure it with the appropriate bolts. Torque them to the manufacturer's specifications.
Reinstall the brake rotor and caliper, securing them with the correct bolts.
Place the wheel back on and hand-tighten the lug nuts.

7. Lower Vehicle

Remove jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the specified value.
