Solution

1. Preparation

Park the vehicle on a level surface and turn off the engine.
Gather all necessary tools and parts.
Ensure safety gear is worn (gloves, safety glasses).

2. Tire Inspection

Tools Required: Tire pressure gauge, flashlight.
Check each tire for proper inflation and tread wear.
Rotate tires if uneven wear is found, and replace damaged tires as needed.

3. Wheel Bearing Inspection

Tools Required: Jack, jack stands, socket set, torque wrench.
Lift the vehicle and securely place it on jack stands.
Grab each wheel at 12 o'clock and 6 o'clock positions and wiggle; check for play.
Rotate the wheel by hand to listen for noise. Replace wheel bearings if necessary.

4. Transmission Fluid Check

Tools Required: Transmission fluid dipstick (if applicable), funnel.
Locate the transmission dipstick (if equipped) and remove it to check fluid level.
Inspect fluid color and smell; it should be red and not burnt.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.

5. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar.
Inspect the driveshaft for any visible damage or corrosion.
Check CV joints for torn boots or grease leakage; replace if damaged.
If necessary, perform a driveshaft balance check.

6. Reassembly and Testing

Reinstall any components removed during inspection and ensure all fasteners are torqued to specifications.
Lower the vehicle and conduct a test drive to verify the repair.
