Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Lift the Vehicle

Use a floor jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to expose the shock absorber.

4. Remove the Old Shock Absorber

Locate the upper and lower mounting bolts of the shock absorber.
Use a socket set to remove the lower mounting bolt first, then the upper mounting bolt.
Carefully pull the shock absorber out of its mount.

5. Install the New Shock Absorber

Position the new shock absorber into the mount.
Insert and hand-tighten the upper mounting bolt first, followed by the lower mounting bolt.
Torque the bolts to the manufacturer's specifications (typically around 30-40 Nm for upper and 50-60 Nm for lower, but verify in the service manual).

6. Reinstall the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts, then use a torque wrench to tighten them to the manufacturer's specifications (usually around 120 Nm).

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle with the floor jack.

8. Repeat for Other Shocks

Repeat steps 2-7 for the remaining shock absorbers as needed.
