Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, fluid pump.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before working underneath.

2. Inspect Tires

Remove the wheel covers or hubcaps if present.
Check all tires for uneven wear, bulges, or foreign objects.
Replace any worn or damaged tires as necessary.

3. Check Wheel Bearings

Lift the vehicle and remove the wheels.
Spin the hub and listen for any grinding or unusual noises that indicate worn bearings.
Replace any faulty wheel bearings using a bearing puller and follow the manufacturer's specifications for torque settings.

4. Examine Transmission Fluid

Locate the transmission dipstick or access point.
Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
If low, add the recommended transmission fluid type until it reaches the appropriate level.

5. Inspect Drive Belts

Visually check the belts for cracks, fraying, or signs of wear.
Use a tension gauge to check belt tension; adjust or replace belts as needed.

6. Test Power Steering System

Check power steering fluid levels and top off with the manufacturer-recommended fluid if low.
Inspect the power steering pump for leaks or unusual noises. Replace if necessary.

7. Inspect the Differential (if applicable)

Check the differential fluid level and condition through the fill plug.
Add or replace with the correct type of differential fluid if needed.
