They say that the original mount is a hydraulic mount which is why it leaks the yucky oil when it breaks, the TSB you are referring to replaces the original hydraulic mount with a solid rubber mount which in turn is a lot more rigid minimizing vibration at crusing speeds but because of its rigidy it doesnt damper as well as the hydraulic mount when iddling.

Replying to: 5_more (Mar 10, 2009 2:19 pm) According to the bulletin it suppose to, although I have never hear of anyone opting to delete the 50mph vibration and instead get a more pronounced iddle vibration... as it is our engines are not the most smooth dampened engines. It's a game of give and take...I guess.
