A rear end that sits low, cracked or broken leaves, or heavy rust can mean a spring has worn out. These signs alone do not prove the spring is to blame, since worn shocks also change how the rear rides. Plan to replace the rear springs as a pair: this listing is one spring, and one goes on each side of the rear axle.
