Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery to prevent electrical issues.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel covering the affected shock absorber using a socket set.

3. Remove the Shock Absorber

Locate the upper and lower mounting bolts of the shock absorber.
Use a socket wrench to remove the upper mounting bolt first, followed by the lower mounting bolt.
Carefully pull the shock absorber out of its mounting location.

4. Install the New Shock Absorber

Position the new shock absorber in place.
Insert the lower mounting bolt first, followed by the upper mounting bolt.
Tighten the bolts to the manufacturer’s specified torque (typically around 50-70 lb-ft for upper and 30-50 lb-ft for lower, but refer to the service manual for exact values).

5. Reinstall the Wheel

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and securely tighten the lug nuts to the manufacturer's specified torque.

6. Reconnect the Battery

Reconnect the 12V battery and ensure all connections are secure.
