Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the shock absorber.

2. Remove the Shock Absorber

Disconnect the top mount:
- Locate the top mounting bolts of the shock absorber inside the engine bay or trunk.
- Use a socket set to remove the bolts. Hold the shock shaft with a wrench to prevent it from spinning.
Remove the lower mount:
- Locate the lower mounting bolt at the bottom of the shock absorber connected to the control arm.
- Use a socket set to remove this bolt.
Extract the shock absorber:
- Carefully pull the shock absorber out from its mounting position. Be mindful of any attached components.

3. Inspect and Replace

Inspect the shock:
- Check the shock absorber for any additional damage or wear.
Install the new shock absorber:
- Position the new shock absorber in place of the old one, ensuring it aligns with the mounting points.
Reattach the lower mount:
- Insert the lower mounting bolt and tighten it to the manufacturer’s specifications (typically around 40-50 Nm).
Reattach the top mount:
- Position the top of the shock absorber in its mount and secure it with the bolts. Tighten to the recommended torque specifications (usually around 25 Nm).

4. Final Assembly

Reinstall the wheel and lower the vehicle from the jack stands.
Torque the wheel bolts to the manufacturer’s specification (typically around 120 Nm).
