Solution

1. Tire Inspection and Replacement

Visual Inspection: Examine all tires for signs of wear, bulges, or foreign objects.
Tire Rotation: If uneven wear is detected, rotate the tires to promote even wear.
Replacement: If any tires are damaged beyond repair, replace them with OEM or quality aftermarket tires.

2. Brake Component Inspection and Repair

Remove Wheel: Utilize a jack and jack stands to lift the vehicle and remove the wheel.
Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; replace if worn below manufacturer's specifications.
- Inspect rotors for scoring or warping; machine or replace if necessary.
Reassemble: Reinstall the wheel and lower the vehicle to the ground.

3. Engine Belt Inspection and Replacement

Visual Inspection: Check all belts for signs of wear, fraying, or glazing.
Tension Check: Ensure the belts are properly tensioned; adjust or replace tensioners if necessary.
Replace Belts: If any belt shows significant wear, replace with OEM belts.

4. Clean Undercarriage

Visual Check: Inspect under the vehicle for debris or objects that may be causing friction.
Cleaning: Remove any debris using a scraper or soft brush.
