Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect each tire for uneven wear, bulges, or foreign objects lodged in the tread.
3. Check tire pressure and inflate to the manufacturer's specifications if necessary.
Tools Required: Tire pressure gauge, tire inflator.

3. Wheel Bearing Inspection

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Spin each front wheel by hand and listen for unusual noises or roughness.
3. Grab the wheel at the 12 and 6 o'clock positions and check for any play.
Tools Required: Jack, jack stands.

4. Brake Component Inspection

Sub-steps:
1. Remove the wheel for access to the brake assembly.
2. Inspect brake pads for wear and the rotors for warping or scoring.
3. Clear any debris from the brake components.
Tools Required: Socket set, brake cleaner.

5. Drive Belt Inspection

Sub-steps:
1. Locate the drive belts and visually inspect for cracks, fraying, or signs of wear.
2. Check belt tension and adjust or replace if necessary.
Tools Required: Torque wrench (if adjusting), replacement belts (if needed).

6. Fluid Level Verification

Sub-steps:
1. Check the transmission fluid level using the dipstick; add fluid if low.
2. If the differential is accessible, check the fluid level and top it off if necessary.
Tools Required: Transmission fluid, differential fluid, fluid pump.
