Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and wear safety goggles.
Gather tools: jack, jack stands, socket set, torque wrench, and a pry bar.

2. Raise the Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to ensure stability.

3. Inspect Suspension Components

Shock Absorbers: Remove the bolts securing the shock absorbers. Inspect for leaks or physical damage. Replace if necessary.
Bushings: Check all suspension bushings for cracks or deterioration. Replace any damaged bushings.
Ball Joints: Use a pry bar to check for excessive play in the ball joints. Replace if any movement is detected beyond manufacturer specifications.

4. Examine and Replace Tires (if necessary)

Check tires for uneven wear; replace if necessary.
Ensure all tires are properly inflated to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reattach all components that were removed for inspection or replacement.
Ensure all bolts are tightened to the manufacturer’s torque specifications.
Carefully lower the vehicle back to the ground.
