Solution

1. Preparation

Gather tools including a jack, jack stands, lug wrench, and socket set.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which wheel bearings you are inspecting.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Use the lug wrench to loosen and remove the lug nuts from the wheel.
Carefully remove the wheel and set it aside.

4. Inspect the Wheel Bearing

Locate the wheel bearing hub assembly. Inspect for any signs of damage or excessive wear.
Spin the hub by hand to check for smoothness; it should rotate freely without noise.

5. Replace the Wheel Bearing (if necessary)

If the bearing is bad, remove the brake caliper and rotor by unbolting them. Secure the caliper with a wire or bungee to avoid stress on the brake line.
Remove the wheel hub assembly by unbolting it from the steering knuckle.
Replace the wheel bearing by pressing a new bearing into the hub assembly using a bearing press. Ensure it is seated correctly.
Reassemble by reversing the disassembly steps, ensuring all bolts are tightened to manufacturer specifications (typically around 75-100 ft-lbs for hub assembly bolts).
