Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Pry bar
- Jack and jack stands
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Worn Suspension Components

Raise the Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheels:
- Use a socket set to remove the lug nuts and take off the wheels for better access to the suspension components.
Inspect Suspension Parts:
- Check the condition of the shocks/struts, bushings, control arms, ball joints, and sway bar links for signs of wear or damage.
- Use a pry bar to check for excessive movement in the ball joints and bushings.
Replace Damaged Components:
- If any components are found to be worn or damaged, remove them using the socket set.
- Install new parts according to manufacturer specifications, ensuring to torque bolts to the recommended values.
- For shocks/struts, ensure proper alignment of all mounting points.

3. Reassemble and Lower Vehicle

Reinstall the wheels and torque the lug nuts to the specified torque rating.
Carefully lower the vehicle back to the ground.
