A bouncy ride, fluid on the shock body or a rear end that bottoms out over bumps can mean the shock is worn, though worn tires or a worn rear spring can be behind the same signs, so find the cause before replacing it. The pack holds two shocks, which gives the 1983-2011 Ford Ranger a pair for the rear; fit both together.
