Solution

1. Preparation

Tools Required: Jack and jack stands, tire pressure gauge, torque wrench, alignment machine.
Park the vehicle on a level surface and engage the parking brake.
Gather all necessary tools and parts.

2. Tire Inspection and Replacement (if needed)

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate to manufacturer's recommended PSI if low.
2. Inspect tires for tread wear and damage; replace any tires that are worn or damaged.
3. If replacing, remove the wheel using a socket set and torque wrench to loosen lug nuts.
4. Install new tires, ensuring to torque lug nuts to the manufacturer's specifications.

3. Suspension Component Replacement (if needed)

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect and replace worn shocks or struts:
  - Detach the top and bottom mounting bolts of the strut/shock using a socket set.
  - Install the new shock/strut and tighten the bolts to the specified torque value.
4. Replace any damaged bushings or control arms by removing the old components and installing new ones.

4. Alignment

Sub-steps:
1. After replacing tires and/or suspension components, take the vehicle to a professional alignment shop.
2. Ensure all specifications meet manufacturer requirements for optimal handling.
