Solution

1. Preparation

Gather tools and parts needed for inspection.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Tire Inspection

Remove the wheel covers or hubcaps (if equipped).
Inspect the tread depth and wear pattern on all tires.
Check for any visible damage such as cuts, bulges, or foreign objects embedded in the tires.
Rotate or replace tires if any irregularities are found.

3. Wheel Bearing Inspection

Lift the vehicle using a jack and secure it on jack stands.
Grasp the wheel at the 12 and 6 o’clock positions, then rock it back and forth to check for play.
Spin the wheel while listening for any grinding or roughness.
Replace any worn or damaged wheel bearings.

4. Drivetrain Components Examination

Inspect the driveshaft and CV joints for any signs of wear or damage.
Check the differential for proper lubrication and signs of leaks.
Replace any faulty components as necessary.

5. Transmission Fluid Check

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and remove again to check the fluid level.
Inspect the fluid for color and smell (should be a bright red color and not burnt).
Change the transmission fluid if it appears dirty or low.
