Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel using a socket set.

3. Remove the Brake Components

Remove the brake caliper by loosening the caliper bolts using a socket wrench.
Hang 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.

4. Inspect and Remove the Wheel Bearing Hub Assembly

Locate the wheel bearing hub assembly.
Remove any dust caps and cotter pins if applicable.
Unscrew the hub assembly bolts using a torque wrench and remove the hub from the steering knuckle.
If necessary, use a bearing puller to extract the old bearing.

5. Install New Wheel Bearing

Clean the mounting surface of the steering knuckle.
Position the new wheel bearing into the hub and secure it with the bolts, torquing to the manufacturer's specifications.
Reinstall the hub assembly onto the steering knuckle and secure it.

6. Reassemble Brakes and Wheel

Reattach the brake rotor and caliper.
Ensure all bolts are tightened to the manufacturer's torque specifications.
Reinstall the wheel and lower the vehicle.

7. Final Checks

Reconnect the negative battery terminal.
Test the vehicle at low speeds to ensure proper installation and functionality.
