Solution

1. Tire Inspection and Pressure Adjustment

Inspect all tires for uneven wear patterns or visible damage.
Measure tire pressure using a tire pressure gauge and adjust to the recommended PSI as listed in the owner's manual.

2. Suspension Component Inspection

Lift the vehicle using a hydraulic jack and secure it with jack stands.
Visually inspect each suspension component for signs of wear, cracks, or leaks.
Check the condition of the shock absorbers/struts for damping efficiency.

3. Wheel Alignment

Use a professional wheel alignment machine to check the alignment settings.
Adjust the camber, caster, and toe angles as necessary to meet manufacturer specifications.

4. Replace Worn Suspension Components (if needed)

If any suspension components are found to be worn or damaged, replace them as follows:
- Remove the old component: Use a socket set to remove bolts securing the component.
- Install the new component: Position the new part and secure it using the specified torque values (refer to the service manual for exact specifications).

5. Final Inspection and Test Drive

After completing repairs or adjustments, lower the vehicle and perform a final visual inspection.
Take the vehicle for a test drive on the highway to assess ride quality and handling.
