Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off, and the vehicle is cool.

2. Inspect and Tighten Wheels

Sub-steps:
1. Using a lug wrench, loosen the lug nuts on all four tires.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Inspect the lug nut torque specifications in the owner's manual.
4. Tighten lug nuts in a crisscross pattern to the specified torque (typically 100-150 ft-lbs).

3. Check Tires

Sub-steps:
1. Examine each tire for signs of uneven wear or damage (bulges, cuts).
2. Measure tire pressure with a tire gauge and adjust to the recommended PSI.
3. Rotate tires if needed, based on wear patterns.

4. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional shop for alignment and balancing.
2. Ensure all wheels are balanced properly to eliminate vibrations.

5. Driveshaft Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or looseness.
2. Check universal joints for wear or play and replace if necessary.

6. Suspension Check

Sub-steps:
1. Inspect shocks and struts for leaks and signs of wear.
2. Check all bushings for cracks or deterioration.
3. Replace any worn components as needed.
