a dynamic damper is a device intended to damp out a vibration by setting up forces to oppose the vibrational motion.
there is no rubber left when going to es or sold subframe bushings. Not sure what you are referring to. All the stock rubber is removed when doing the swap to either of those other bushings. Many people burn them out but there are easier/better/faster ways. I personally use a hole saw and sawzall to get the old bushing and sleeve out.Luminar said:dave, you do not want to burn them out, there is an outer sleeve of metal that the OEM bushing is pressed into, between this outermost shell and the subframe itself, is a wall of solid rubber about 1.5mm thick. This MUST remain to use the ES bushings. burning them out would hurt this rubber. Plus the oem ones are filled with silicon goo, i cant imagine burning them is a good idea.
