Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface, and park it securely.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle at the designated lift points.
Secure with jack stands to ensure safety while working under the vehicle.

3. Inspect and Replace Shock Absorbers

Remove the wheel:
- Use a socket set to remove the lug nuts and take off the wheel.
Remove the shock absorber:
- Locate the top mounting bolts of the shock absorber inside the trunk or under the hood (for rear or front shocks respectively).
- Use a wrench to remove the bolts.
- Remove the lower mounting bolt at the base of the shock, using a socket or wrench.
Install new shock absorbers:
- Position the new shock absorber in place.
- Tighten the lower bolt to the manufacturer's specified torque (usually around 50-60 ft-lbs but check the service manual).
- Reinstall the top mounting bolts and secure them.

4. Check and Replace Other Suspension Components

Inspect control arms, bushings, and sway bar links for wear.
Replace any worn bushings or components using similar steps as above, with attention to proper torque specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

6. Test Drive

Conduct a test drive to evaluate the repair and ensure the shaking has been resolved.
