Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and securely raise it with jack stands.
Disconnect the battery if working on electronic suspension components.

2. Tire Inspection and Replacement

Check Tire Pressure:
- Use a tire pressure gauge to ensure all tires meet manufacturer specifications.
Inspect and Replace Tires:
- Remove lug nuts using a socket set and take off the tires.
- Inspect tread depth and sidewalls for damage.
- If tires are worn or damaged, replace them with new ones of the same specifications.
- Reinstall tires and torque lug nuts to the manufacturer's specifications (typically 75-80 ft-lbs).

3. Suspension Inspection and Repair

Inspect Suspension Components:
- Examine struts and shocks for fluid leaks and physical damage.
- If any components are worn, replace them as necessary using a spring compressor if needed.
Replace Worn Components:
- Remove old struts or shocks by unbolting from the mounting points.
- Install new struts or shocks, ensuring proper alignment with mounting holes. Torque bolts to manufacturer specifications.

4. Wheel Alignment

Perform Wheel Alignment:
- Use alignment equipment to assess and adjust the alignment angles.
- Adjust toe, camber, and caster settings to factory specifications.
