Solution

1. Preparation

Gather tools: jack and jack stands, socket set, torque wrench, brake cleaner, and a flashlight.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery for safety when working near electrical components.

2. Inspect and Replace Brake Pads (if necessary)

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a socket set.
Inspect brake pads for thickness. If pads are less than 3mm, replace them.
To replace pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it using a bungee cord.
- Remove old brake pads and replace with new ones.
- Reassemble caliper and wheel, ensuring to tighten bolts to manufacturer specifications.

3. Check and Replace Serpentine Belt (if necessary)

Locate the serpentine belt and check for cracks or wear.
If damage is present:
- Use a socket wrench to relieve tension from the belt tensioner.
- Remove the old belt from pulleys.
- Install a new serpentine belt, following the correct routing diagram typically found on the engine cover.
- Reapply tension and ensure the belt is properly seated.

4. Inspect Suspension Components

Visually check struts and shock absorbers for leaks or damage.
Inspect bushings for cracks or deterioration.
If components are worn:
- Remove the affected parts using a socket set.
- Replace with new parts, ensuring to follow torque specifications during installation.

5. Examine Wheel Bearings

Lift the vehicle and shake the wheel at 12 and 6 o'clock to check for play.
If play is detected:
- Remove wheel and brake components as necessary.
- Replace the bearing assembly if roughness or wear is present.
- Reassemble all components and ensure everything is torqued properly.
