A rear end that sags under load, a bouncy or floating ride, or fluid on the shock body can mean the shock absorber is worn, though worn rear springs or loose mounts can also be behind them, so find the cause before replacing it. Load capacity is limited by the vehicle's suspension, tires and transmission; see the owner's manual.
