2. Unscrew the top strut mount bolts within the trunk area.
3. Extract the strut from the vehicle.

5. Install New Struts

Front Struts:
1. Insert the new strut into the mounting location and secure it with the top mount bolts.
2. Attach the strut to the steering knuckle and tighten bolts to manufacturer specifications.
Rear Struts:
1. Position the new strut in place and secure it to the rear axle.
2. Fasten the top mount bolts in the trunk area.

6. Reassemble and Check

Reattach the wheels and tighten the lug nuts to the specified torque.
Lower the vehicle from the jack stands and perform a final check on all fasteners.
