Solution

1. Preparation

Gather tools including a jack, jack stands, tire pressure gauge, and basic hand tools.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal if working on electronic components.

2. Tire Inspection and Replacement

Sub-steps:
1. Use a tire pressure gauge to check and adjust tire pressures to manufacturer specifications.
2. Inspect the tires for uneven wear patterns; replace if necessary.
3. If tire replacement is required, use a jack to lift the vehicle and remove the wheel.
4. Install new tires, ensuring proper torque (usually around 80-100 ft-lbs).

3. Suspension Component Inspection and Repair

Sub-steps:
1. Lift the front and rear of the vehicle with a jack and secure with jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect shocks/struts for leaks; replace if damaged. Use a socket set to remove the mounting bolts.
4. Replace any worn bushings or control arms as necessary.
5. Reinstall wheels and lower the vehicle.

4. Alignment Adjustment

Sub-steps:
1. After suspension repairs, take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment to ensure proper angles for the suspension geometry.
