Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather all required tools and parts before starting.
Tools Required: Jack, jack stands, socket set, torque wrench, wheel chocks, and a bearing puller (if necessary).

2. Lift and Secure the Vehicle

Use a jack to lift the vehicle and place it on jack stands.
Place wheel chocks on the opposite wheels to prevent rolling.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Safety Warning: Ensure the vehicle is securely supported on jack stands before working underneath.

4. Remove the Brake Components

Remove the brake caliper by detaching the mounting bolts. Support it using a bungee cord to avoid stressing the brake line.
Remove the brake rotor by taking off any retaining screws or clips.

5. Remove the Wheel Hub Assembly

If necessary, detach the axle nut using a suitable socket. You may need to apply penetrating oil if it is rusted.
Remove the wheel hub assembly by unbolting it from the suspension components. Use a bearing puller if needed.

6. Inspect and Replace the Wheel Bearing

Inspect the bearing for signs of wear or damage. If it feels rough or has play, it needs replacement.
Install the new wheel bearing into the hub assembly, ensuring it is seated properly.
Reassemble the wheel hub assembly by reversing the removal steps.

7. Reinstall Brake Components and Wheel

Reinstall the brake rotor and caliper, ensuring all bolts are tightened to the manufacturer’s specifications.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
