Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift it using a hydraulic jack and jack stands.
Disconnect the battery to avoid any electrical issues.

2. Remove the Shock Absorber

Step 1: Remove the wheel corresponding to the shock absorber to gain access.
Step 2: Use a socket set to remove the lower mounting bolt of the shock absorber.
Step 3: Remove the upper mounting bolts from the top of the shock absorber, which may require accessing through the trunk or under the hood.
Step 4: Carefully slide the shock absorber out of its mount.

3. Install New Shock Absorber

Step 1: Align the new shock absorber in the mount and insert it into place.
Step 2: Secure the upper mount with the bolts, tightening them to the manufacturer's specified torque (usually around 30-40 Nm, but check service manual for exact value).
Step 3: Reattach the lower mounting bolt and tighten to the specified torque (typically around 50-70 Nm).
Step 4: Reinstall the wheel and lower the vehicle back to the ground.
