Suspension bushings are being discussed. Technician A says the rubber bushings used in a control arm flex and twist as the control arm moves up and down. Technician B says rubber bushings should be lubricated with petroleum-based lubricants every 30,000 miles. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because rubber bushings in a control arm are designed to flex and twist to accommodate the movement of the control arm. This flexibility helps to absorb road shocks and vibrations, providing a smoother ride. Technician B is incorrect because petroleum-based lubricants can actually degrade rubber bushings over time. It's generally recommended to avoid using petroleum-based products on rubber components in vehicles.
