Why replace them and typical age-related failures: Cracked or perished rubber → rear-end clunks, squeaks, and “rear-steer” feel on throttle/brake. Ovalised inner sleeve → unstable alignment; car wanders and tramlines. Oil/heat-swollen rubber → excess compliance and braking instability. Replacing restores correct alignment, handling and braking stability  

Common issues you’ll see Play at the trailing-arm pivot (visible with a pry bar); torn rubber. Uneven rear-tyre wear (inside edges from toe change under load). Noisy rear suspension over small bumps. Alignment won’t hold after a set-up (bushings deflect back).
