Solution

1. Preparation

Gather tools and parts needed for inspection.
Tools Required: Floor jack, jack stands, lug wrench, socket set, torque wrench.
Safety Warnings: Always ensure the vehicle is securely lifted and supported before working underneath.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the wheel while the vehicle is still on the ground.
Lift the vehicle using a floor jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect Wheel Bearing

Check for any visible damage or excessive wear on the wheel bearing and hub assembly.
If there is play detected, proceed to replace the wheel bearing.
Use a socket set to remove the caliper and rotor if needed for better access.

4. Replace Wheel Bearing (If Necessary)

If the bearing is faulty, use a bearing puller to remove the old bearing from the hub assembly.
Clean the hub area thoroughly before installing the new bearing.
Apply a suitable grease to the new bearing and press it into place or install as per manufacturer specifications.

5. Reassemble

Reattach the brake rotor and caliper, ensuring all bolts are torqued to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and tighten the lug nuts in a star pattern to the specified torque.
