2014 SE TRD rear sway bar installation problem - Toyota Yaris Forums

Just to be clear: These are not bump stops. They are just vibration dampeners to deal with NVH. Basically some chassis engineer found that in that area of the vehicle there was a vibration that may cause excess noise to the driver. So they bolt a dampener in place because it's cheaper than making new axle assemblies. Chances are you can remove the dampener and never notice any noise difference.

That's interesting. I have wondered about their purpose since I discovered them. So is this the "official" explanation? If so how did you come by this info?
