Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Wear safety glasses and gloves for protection.

2. Tire Inspection

Remove the wheel covers or hubcaps if applicable.
Use a tire pressure gauge to check tire pressure and adjust as needed.
Visually inspect the tires for any signs of uneven wear, bulges, or foreign objects embedded in the tread.

3. Wheel Bearing Inspection

Use a jack to lift the vehicle and secure it with jack stands.
Grasp the wheel at the 12 and 6 o'clock positions, attempting to rock it back and forth to check for play.
If play is detected, remove the wheel and inspect the wheel bearing for wear or damage.

4. Drive Belt and Pulleys

Locate the drive belt and inspect for signs of wear such as cracks or fraying.
Use a wrench to rotate the tensioner and release tension on the drive belt.
Inspect the pulleys for wear or misalignment, ensuring they spin freely.

5. Transmission Fluid Check

Locate the transmission dipstick (if equipped) and remove it.
Wipe it clean, reinsert, and remove again to check the fluid level.
If low, add the recommended transmission fluid type specified in the owner’s manual.

6. Differential Fluid Inspection

Locate the differential fill plug and remove it.
Check the fluid level by inserting a finger; it should be just below the fill hole.
If the fluid is low, add the appropriate differential fluid until it reaches the correct level.
