Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during the repair.

2. Lift the Vehicle

Using a hydraulic floor jack, lift the vehicle and secure it with jack stands under the frame.
Remove the relevant wheel for easier access to the shock absorber.

3. Remove the Old Shock Absorber

Locate the mounting bolts on the top and bottom of the shock absorber.
Use a socket wrench to remove the upper mounting bolt first, followed by the lower mounting bolt.
Carefully detach the shock absorber from its mounts and remove it from the vehicle.

4. Install the New Shock Absorber

Position the new shock absorber in place, aligning it with the mounting points.
Install the lower mounting bolt first, tightening it to the manufacturer's specified torque (typically around 40-60 Nm).
Attach the upper mounting bolt and tighten to the recommended torque.

5. Reassemble the Suspension

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications (usually around 120 Nm).

6. Final Checks

Reconnect the battery.
Check for any leaks around the new shock absorber.
Test drive the vehicle to ensure proper installation and functionality.
