Unless you have a press or priority is to upgrade the ENTIRE front suspension, you are looking for a considerable amount of extra work to remove the existing bushing. It is far easier to purchase the tension strut with the bushing installed. The bushing can be removed with a sazall though you have to be very careful not to damage the tension strut by cutting to deep or at an angle. If you decide to replace just the bushing and don't have a press there is a ball joint tool you can purchase or rent that will also press out the bushing.
