Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Tire Inspection and Replacement

Inspect Tires:
- Check tire pressure using a pressure gauge; inflate to the manufacturer’s recommended PSI.
- Inspect for uneven wear patterns; replace any tires that are excessively worn.
Replace Tires:
- If necessary, remove lug nuts using a socket set and replace with new tires.
- Torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Suspension Component Inspection and Replacement

Inspect Suspension:
- Use a jack to lift the vehicle and secure it with jack stands.
- Visually inspect struts, shocks, and bushings for wear; replace any damaged components.
Replace Suspension:
- Remove the old strut or shock using a socket set.
- Install the new strut or shock, ensuring all bolts are torqued to specifications (usually around 35-45 ft-lbs).

4. Wheel Alignment

Perform Wheel Alignment:
- After replacing tires and inspecting suspension, use an alignment machine to adjust camber, caster, and toe to manufacturer specifications.
- Adjustments may require special tools like a torque wrench and alignment tools.
