Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Safely lift the vehicle using a jack and secure it on jack stands.
Ensure the workspace is clear and well-ventilated.

2. Inspect and Replace Worn Components

- Use a pry bar to check for play in the control arms and bushings.
- Check shock absorbers or struts for signs of leakage or physical damage.
Replace Damaged Components:
- If any components are found damaged, remove them using the socket set.
- Install new suspension parts, ensuring they are torqued to the manufacturer's specifications.
- Typical torque values for suspension components may range from 40-70 ft-lbs; consult service manual for specifics.

3. Reassemble and Lower the Vehicle

Ensure all components are securely fastened and torqued.
Remove jack stands and carefully lower the vehicle back to the ground.
