Two technicians are discussing the replacement of a rebound or jounce bumper. Technician A says if a vehicle fails the jounce test the cause is a defective jounce bumper. Technician B says you need to remove the lower ball joint to replace the jounce bumper on an SLA (short arm long arm) suspension. Who is right?

ASE identifies suspension and steering as an individual service area for certification. The suspension and steering service area involves the following components: Steering system, Suspension system, Wheel Alignment and Wheel and Tire Service.
