Solution

1. Preparation

Tools Required: Jack and jack stands, tire pressure gauge, alignment machine, socket set, torque wrench.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery if working on electronic steering components.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the hubcaps or wheel covers, if applicable.
2. Loosen the lug nuts slightly (do not remove them yet) using a socket wrench.
3. Raise the vehicle with a jack and secure it with jack stands.
4. Remove the lug nuts and take off the tires.
5. Check tire tread depth and sidewall for damage. Replace any tires that are worn or damaged.
6. Reinstall tires and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Use an alignment machine to check the alignment settings.
2. Adjust the camber, toe, and caster according to manufacturer specifications.
3. Perform a test drive to ensure the vehicle tracks straight.

4. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect shocks and struts for leaks, dents, or damage.
2. If any component is found faulty, remove it using a socket set and replace with new parts.
3. Check and replace worn bushings or mounts as needed.
4. Torque all suspension components to manufacturer specifications.

5. Steering System Check

Sub-steps:
1. Inspect tie rods and steering rack for excessive play or damage.
2. Replace any worn components as necessary.
3. Ensure that all connections are tight and torqued to specifications.
