Used components are pulled directly from a vehicle – typically a junkyard vehicle – and generally not even so much as surface cleaned. There are no provisions for dis-assembly, internal cleaning or inspection with a used component.  Used or junkyard components may have high mileage and a poor maintenance history – a failure waiting to happen. Many used or junkyard components come from a vehicle that was involved in an accident and may have unseen damage such as being immersed in water.
