Subaru Forester: spring coating damage, corrosion and a low body corner

Coating damage, corrosion, then a broken coil section

Subaru describes stones and road debris damaging the spring’s outer coating, followed over time by possible pitting and separation of a small section. A fragment beside a parked car or a lower body corner may be noticed. These are possible signs, not a diagnosis from one symptom.

Spring and damper require separate evidence

Strut repair does not identify the component worked on. Record spring, damper, mounts and fasteners separately. A fractured spring does not prove damper failure; an invoiced damper replacement does not prove crash-caused spring breakage.

Editorial inspection order.
