Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools, including a socket set, torque wrench, and jack stands.

2. Inspect and Tighten Components

Sub-steps:
- Open the hood and visually inspect the serpentine belt for signs of wear, such as cracking or fraying.
- Use a socket set to tighten any loose bolts on the engine components, including the alternator and idler pulleys.
- If the serpentine belt is worn, proceed to replace it (see step 3).

3. Replace Serpentine Belt (if needed)

Sub-steps:
- Loosen the tensioner pulley using a wrench and remove the old belt.
- Route the new serpentine belt according to the engine diagram (usually located near the radiator or on the engine cover).
- Ensure the belt is properly seated on all pulleys and tighten the tensioner.

4. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel and inspect the wheel bearing for play by shaking the wheel.
- If the bearing is worn, remove the hub assembly and replace the bearing with a new one, ensuring proper torque specifications.

5. Check and Replace Brake Components (if applicable)

Sub-steps:
- Remove the wheel and inspect the brake pads for thickness and even wear.
- If pads are worn beyond the minimum specification, replace them with new ones, ensuring to lubricate the caliper slides.
- Inspect the rotors for scoring or warping; replace if necessary.

6. Inspect Tires

Sub-steps:
- Check tire pressure and inflate to the manufacturer’s specifications.
- Inspect tread for uneven wear; rotate or replace tires as necessary.
