Solution

1. Inspection

Tools Required: Jack, jack stands, lug wrench, flashlight
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheels with a lug wrench for better access to brakes and bearings.
Inspect brake pads for wear and rotors for scoring or damage.

2. Brake Pad Replacement (if worn)

Parts Required: New brake pads, brake cleaner, anti-squeal lubricant
Remove the caliper bolts and slide the caliper off the rotor.
Replace worn brake pads with new ones, ensuring they are properly seated.
Reinstall the caliper and torque the bolts to manufacturer specifications (usually around 20-30 ft-lbs).

3. Serpentine Belt Inspection/Replacement

Tools Required: Serpentine belt tool or wrench
Inspect the serpentine belt for cracks, fraying, or glazing.
If damaged, remove the tensioner and replace the serpentine belt, making sure it is properly routed according to the diagram on the engine bay.

4. Power Steering Fluid Check

Tools Required: Funnel, power steering fluid
Check the power steering fluid level; if low, top off with the manufacturer-recommended fluid.
Inspect power steering pump and hoses for leaks or wear.

5. Wheel Bearing Inspection (if necessary)

Tools Required: Bearing puller (if replacement is needed)
Spin the wheel to listen for noise; excessive play indicates a worn bearing.
If found faulty, replace the wheel bearing according to service manual specifications.
