A rear end that sits low or leans, a cracked or broken leaf, or heavy rust on the pack can mean a spring has worn out. Before you replace one, walk around the vehicle on level ground with the engine off and compare both sides, since a worn shackle or bushing can look similar and a shop can test what you can't see.
