Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar
Safely lift the vehicle and secure it on jack stands to prevent accidents.
Ensure all tools and parts are within reach.

2. Inspect and Replace Worn Suspension Components

Inspect Control Arms:
- Use a pry bar to check for any movement or play in the control arms.
- If damaged, remove the bolts securing the control arm to the chassis and the ball joint.
- Replace with a new control arm, tightening bolts to manufacturer specifications.
Check Shock Absorbers/Struts:
- Remove the wheel to access the shock absorber.
- Inspect for leaks or physical damage.
- If faulty, detach the top and bottom mounting bolts and replace with a new shock absorber, ensuring proper torque specifications.
Examine Sway Bar Links:
- Locate and assess the sway bar links for wear.
- Remove any damaged links and replace with new ones, tightening to the specified torque.

3. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Perform a final check to ensure all components are securely fastened.
