Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a hydraulic floor jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to prevent any accidents.

3. Inspect and Replace Suspension Components

Shock Absorbers
- Remove the lower mounting bolts and disconnect the shock from the lower control arm.
- Remove the top mounting nut from the shock tower.
- Replace with new shock absorbers, ensuring they are seated properly.
Sway Bar Links
- Remove the sway bar link bolts using a socket wrench.
- Inspect the bushings and replace them if cracked or worn.
- Reinstall the new sway bar links and tighten to manufacturer specifications (typically around 35-45 Nm).

4. Tighten Bolts and Fasteners

Use a torque wrench to check and tighten all suspension bolts to the manufacturer's specifications, including control arm bolts and sway bar mounting points.

5. Reassemble and Lower Vehicle

Reinstall any components removed for access.
Carefully lower the vehicle back to the ground and remove the jack stands.
