Sub-steps:
1. Remove the wheel covers and loosen the lug nuts with a socket set.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheels and inspect tires for uneven wear or damage.
4. If tires are worn, replace them with new tires that meet the manufacturer’s specifications.
5. Reinstall wheels and torque lug nuts to manufacturer specifications (usually around 100 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure the alignment is set to manufacturer specifications.
3. Verify that all adjustment angles (camber, caster, toe) are within acceptable ranges.

4. Suspension Component Replacement

Sub-steps:
1. Inspect shocks and struts for leaks or physical damage.
2. If worn, remove the old shocks/struts using a socket set and replace with new units.
3. Check control arms and bushings for wear; replace as necessary.
4. Reassemble components and ensure all bolts are torqued to specifications.

5. Steering System Inspection and Repair

Sub-steps:
1. Check tie rods for play by manually shaking them; replace if any movement is detected.
2. Inspect the steering rack for leaks or damage; replace if necessary.
3. After repairs, ensure that all components are properly secured.
