Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Disconnect the battery before working on electrical components.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle from the designated lift points.
Secure with jack stands for safety.

3. Inspect and Replace Components

A. Suspension Components

Inspect:
- Check struts and shocks for leaks or physical damage.
- Look for worn bushings and replace if necessary.
Replace (if needed):
- Struts/Shocks: Remove the bolts securing the struts to the knuckle and the upper mounts. Install the new struts/shocks and torque bolts to manufacturer specifications (typically around 40-60 ft-lbs).

B. Sway Bar Links and Bushings

Inspect:
- Examine sway bar links for play or wear.
Replace (if needed):
- Remove the old sway bar links by unscrewing the bolts. Install new sway bar links and torque to specifications (around 15-25 ft-lbs).

C. Control Arms and Ball Joints

Inspect:
- Check for any excessive play in the ball joints and control arms.
Replace (if needed):
- Remove the control arm bolts and detach the control arm. Install the new control arm and torque bolts to specifications (typically around 65-85 ft-lbs).

4. Reassemble and Lower Vehicle

Reattach any components removed during inspection and replacement.
Ensure all hardware is tightened to the correct torque specifications.
Carefully lower the vehicle back to the ground.
