Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, wrench set, possibly a spring compressor.
Ensure the vehicle is parked on a flat surface and the engine is off.
Place wheel chocks behind the rear wheels to prevent rolling.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which shocks you are replacing.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Loosen and remove the lug nuts using a socket or wrench.
Remove the wheel to access the shock absorber.

4. Remove the Shock Absorber

Locate the top mounting bolts of the shock absorber inside the trunk or under the rear seat for rear shocks, or under the hood for front shocks.
Remove the nuts using a socket or wrench.
At the bottom of the shock, remove the bolt securing the shock to the suspension arm.
Carefully pull the shock absorber out of its mount.

5. Install the New Shock Absorber

Insert the new shock absorber into the mount where the old one was removed.
Secure the bottom bolt first, tightening it to the manufacturer’s torque specification (typically around 40-50 ft-lbs, but check the service manual).
Reinstall the top mounting bolts and tighten them securely.

6. Reinstall the Wheel

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Once on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specification (usually around 76 ft-lbs).

7. Final Inspection

Check the new shocks for proper installation and ensure there are no leaks.
Perform a bounce test to confirm the new shocks are functioning correctly.
