Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Use jack stands to lift the vehicle safely if needed.

2. Inspect and Replace Worn Components

Shock Absorbers:
- Remove the bolts securing the shock absorber at the top and bottom.
- Inspect the shock for leaks or damage.
- Install new shock absorbers, tightening bolts to the manufacturer’s specifications (typically around 50-70 ft-lbs).
Sway Bar Links:
- Remove the nuts securing the sway bar links to the sway bar and lower control arm.
- Inspect the links for play or wear.
- Replace with new sway bar links and torque to manufacturer specifications (generally 30-40 ft-lbs).
Bushings:
- Remove the control arm if bushings are worn.
- Use a bushing removal tool to extract old bushings.
- Install new bushings, ensuring they are properly seated and lubricated.

3. Reassemble and Check

Reattach all components securely.
Double-check torque on all bolts and fasteners.
Reinstall any wheel or suspension covers removed during the process.
