Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.

2. Inspect Suspension Components

Sub-steps:
- Lift the vehicle using a hydraulic jack and secure it on jack stands.
- Visually inspect all visible suspension components for signs of damage or wear (cracks, leaks, or corrosion).
- Use a pry bar to check for any excessive play in bushings and ball joints.

3. Replace Worn Components

Sub-steps:
- If any components are found to be defective, proceed to replace them:
  1. Remove the wheel to gain access to the suspension system.
  2. Disconnect the strut/shock absorber by removing the top and bottom bolts (use a torque wrench to ensure proper torque during reinstallation).
  3. Replace bushings if they are worn by pressing them out and installing new ones using a bushing tool.
  4. Reinstall the new component, following the manufacturer's torque specifications.

4. Alignment

Sub-steps:
- After replacing components, have a professional alignment performed to ensure proper handling and tire wear.
- Adjust toe, camber, and caster as necessary to factory specifications.
