The front suspension strut dampens movement as a vehicle is driven over rough or uneven road surfaces. A vehicle with strut-style suspension has a suspension strut assembly at each wheel, which needs to be replaced if the strut leaks oil or no longer has a dampening effect.
To replace the suspension strut, the wheel is removed from the vehicle. Then the suspension is removed and disassembled (the top spring plate and suspension spring are removed). The old strut is removed and a new one is installed. The suspension is reassembled and reinstalled. To maintain vehicle stability, suspension struts are replaced as a set, so both front suspension struts are replaced at the same time.
