Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery for safety.

2. Inspect and Top Off Fluids

Power Steering Fluid
- Locate the power steering fluid reservoir.
- Check the fluid level; if low, add the manufacturer-recommended fluid.
Transmission Fluid
- Locate the transmission dipstick.
- Pull the dipstick, wipe it clean, reinsert, and check the fluid level. Add fluid if necessary.

3. Inspect and Replace Serpentine Belt

Use a socket set to relieve tension on the serpentine belt tensioner.
Carefully remove the serpentine belt.
Inspect for cracks, fraying, or glazing. Replace if damaged.
Install the new belt, ensuring it follows the correct routing diagram.

4. Check Alternator

Use a multimeter to check the alternator's voltage output (should be between 13.5-14.5 volts when running).
If the alternator is noisy, consider replacing it. Disconnect the battery, and remove the alternator using a socket set.

5. Inspect Wheel Bearings

Raise the vehicle using a jack and secure it with jack stands.
Grab the wheel and check for play; rotate the wheel and listen for rough noise.
If noisy or loose, replace the wheel bearing following manufacturer guidelines.
