Solution

1. Preparation

Required Tools: Jack, jack stands, lug wrench, torque wrench, strut socket set, and a pry bar.
Park the vehicle on a level surface, set the parking brake, and disconnect the 12V battery for safety.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which struts you are replacing.
Place jack stands under the vehicle for additional safety.

3. Remove the Wheel

Use the lug wrench to remove the wheel covering the strut assembly.
Set the wheel aside in a safe location.

4. Remove the Strut Assembly

Locate the upper strut mount and remove the nuts using the appropriate socket. Keep track of the washers and nuts for reinstallation.
Remove the lower strut bolts using a socket and ratchet.
Carefully pull the strut out of the wheel well, using a pry bar if necessary.

5. Install New Struts

Position the new strut in the wheel well and align it with the lower mounting holes.
Insert and hand-tighten the lower strut bolts, ensuring proper alignment.
Reattach the upper strut mount using the original nuts and washers, tightening them to the manufacturer’s specified torque.

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands using the jack and then fully tighten the lug nuts to the specified torque.

7. Final Checks

Reconnect the 12V battery and perform a test drive to ensure everything is functioning correctly.
