Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turn off the ignition.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Inspect and Replace Tires (if necessary)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench

Use a tire pressure gauge to check the tire pressures and inflate them to the manufacturer's specifications if low.
Visually inspect the tires for any signs of damage (cuts, cracks) or uneven wear.
If tires are damaged or excessively worn, remove them using a lug wrench and replace them with new tires.

3. Check and Replace Wheel Bearings (if necessary)

Tools Required: Socket set, torque wrench, bearing puller (if needed)

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel hub.
Spin the hub and listen for grinding noises; if present, the bearing may need replacement.
Remove the old bearing using a bearing puller and install the new bearing following the manufacturer’s specifications.
Reinstall the wheel and torque the lug nuts to the specified value.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Jack, jack stands, socket set

Remove the wheel to access the brake caliper and rotor.
Inspect the brake pads for wear; replace if the thickness is below the minimum specification.
Check the caliper for proper operation; if it's sticking, it may need cleaning or replacement.
Reassemble the brake components and torque to specification.

5. Inspect Undercarriage Components

Tools Required: Socket set, flashlight

Visually inspect the undercarriage for any loose components, such as exhaust hangers or shields.
Tighten any loose bolts or replace damaged parts as necessary.
