A leaking strut body, a bouncy ride or nose-dive under braking can mean a front strut is worn. Those signs alone do not prove the strut is the problem, since a worn control arm bushing can make a car ride rough too. This listing is one front strut assembly; both front sides are normally replaced together, with one strut on each side of the axle.
