Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to prevent any movement while working.

3. Inspect and Replace Suspension Components

Shock Absorbers:
- Remove the bolts securing the shock absorber to the upper and lower mounts using a socket set.
- Carefully remove the shock absorber from the vehicle.
- Install the new shock absorber in the reverse order of removal, ensuring bolts are torqued to manufacturer specifications.
Sway Bar Links:
- Remove the bolts connecting the sway bar links to the sway bar and the lower control arm.
- Inspect the bushings for wear; replace if damaged.
- Install new sway bar links and torque bolts to specifications.

4. Reassemble and Lower Vehicle

Recheck all components and ensure that all fasteners are tightened securely.
Lower the vehicle back to the ground using the hydraulic jack.

5. Final Inspection

Once the vehicle is lowered, check the alignment of the wheels visually.
Ensure there are no loose components and that everything is securely fastened.
