Remove the front or rear wheels, depending on which struts are being replaced.

3. Remove the Old Struts

Front Struts:
1. Disconnect the brake line and any sensor wires attached to the strut.
2. Remove the bolts securing the strut to the steering knuckle using a socket set.
3. Unbolt the strut from the top mount located in the engine bay.
4. Carefully remove the strut from the vehicle.
Rear Struts:
1. Disconnect the brake line and any sensor wires attached to the strut.
2. Remove the bolts securing the lower end of the strut to the axle or trailing arm.
3. Unbolt the strut from the top mount in the trunk area.
4. Carefully extract the strut from the vehicle.

4. Install New Struts

Position the new strut in place and secure it to the top mount first.
Connect the lower end of the strut to the steering knuckle (front) or axle/trailing arm (rear).
Reattach the brake line and any sensor wires to the new strut.
Make sure all bolts are torqued to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle back to the ground.
Reconnect the battery.
Test the vehicle to ensure proper operation of the suspension system.
