Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Inspection

Remove the hubcaps or wheel covers if necessary.
Check for cracks, bulges, or foreign objects in the tires.
Rotate the tires if uneven wear is detected and replace any damaged tires.

3. Fluid Check

Locate the transmission and differential fluid reservoirs.
Use a dipstick or sight glass to check fluid levels.
If low, top off with the manufacturer-recommended fluid and check for leaks.

4. Drive Belt Inspection

Visually inspect the drive belts for fraying or cracks.
Check for proper tension; adjust or replace the belt if necessary.
Use a belt tension gauge if available to ensure correct tension specifications.

5. Wheel Bearing Examination

Lift the vehicle using a floor jack and secure it on jack stands.
Spin each wheel by hand to check for noise or roughness.
If noise or play is present, disassemble the wheel assembly and replace the wheel bearings as needed.
