Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, wheel bearing puller, new wheel bearings, grease, and a hammer.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Brake Components

Detach the brake caliper by removing the caliper bolts (usually 12mm or 14mm).
Secure the caliper to the suspension using wire or a bungee cord (do not let it hang by the brake line).
Remove the brake rotor by unscrewing any retaining screws and pulling it off the hub.

4. Remove Old Wheel Bearing

Use a socket to remove the hub nut (usually 30mm or 32mm).
If necessary, use a wheel bearing puller to extract the old bearing from the hub.
Clean the hub area thoroughly to prepare for the new bearing.

5. Install New Wheel Bearing

Apply a thin layer of grease to the new wheel bearing.
Press or hammer the new wheel bearing into the hub using a bearing installer or a suitable tool.
Reinstall the hub nut and tighten to the manufacturer's specified torque (usually around 150 ft-lbs).

6. Reassemble Wheel and Brake Components

Reattach the brake rotor, ensuring any retaining screws are tightened.
Reinstall the brake caliper and tighten the caliper bolts to the specified torque (usually around 25 ft-lbs).
Put the wheel back on and hand-tighten the lug nuts.

7. Lower Vehicle and Finalize

Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer's specification (typically 76 ft-lbs).
Test the wheel by spinning it to ensure no resistance and checking for noise.
