MOTOR MOUNTS Motor mounts should always be replaced in pairs or sets along with transmission mounts.
Age, oil and grease cause deterioration of the rubber leading to vibration, chatter and failure.
No restoration is complete without new motor mounts. Motor mounts (engine mounts) are used to connect a car engine to the car frame. They are usually made of rubber and metal. The metal portion connects to the engine on one side and to the frame on the other. The rubber is in-between to provide some flexibility (so engine shake doesn't cause the car to shake). Newer cars may use slightly different mounts; however, their purpose is the same. Provide the connection from the engine to the car frame. The number of motor mounts varies from car to car. The motor mounts are located in most cars / trucks on the frame just under the motor. Hope this helps
