Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, mechanic's stethoscope, torque wrench, and a socket set.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery if any electrical components will be removed.

2. Remove Wheel

Loosen the lug nuts on the wheel associated with the suspected bearing issue.
Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Wheel Bearing

Remove Brake Components:
- Use a socket set to remove the caliper bolts and lift the caliper off the rotor.
- Secure the caliper with a bungee cord to avoid straining the brake line.
- Remove the brake rotor by loosening any retaining screws and sliding it off.
Remove Hub Assembly:
- Locate the wheel bearing assembly which is typically integrated into the hub.
- Remove the axle nut using a socket set (ensure to use the correct torque specifications).
- Unbolt the hub assembly from the control arm and steering knuckle.
- Gently tap the hub to free it from the bearing using a rubber mallet.
Install New Wheel Bearing:
- Clean the knuckle and inspect for any debris.
- Press the new wheel bearing into the hub using a bearing press or appropriate tools.
- Align the hub assembly with the steering knuckle and control arm, and bolt it back in place.
- Reinstall the axle nut and torque it to manufacturer specifications.

4. Reassemble Brake Components

Slide the brake rotor back onto the hub.
Reattach the brake caliper and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Final Check

Lower the vehicle from the jack stands.
Use the torque wrench to tighten the lug nuts to the specified torque.
