Which evidence confirms a failed damper on inspection?

  • A.Corrosion of the body
  • B.Free play at the lower mounting bush, which is a normal consequence of the flexing that occurs during operation
  • C.Fluid leakage from the seal around the rod
  • D.A ride height below the specified figure, which indicates that the damper is no longer supporting the vehicle

Answer: C

Oil on the body of the damper means the seal has failed and the unit can no longer generate damping force. A light film is sometimes acceptable but a run of oil is not. Dampers are replaced in pairs across an axle. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. Naming what changes and what stays the same is the reliable route through questions of this shape. Checking which component actually carries the load settles most questions of this kind at once.
