Guest STEVE_BAXR Guests Posted 23/07/09 10:23 PM Share Posted 23/07/09 10:23 PM (edited) I have just put a new diff bush in and I have to say the noise is bad , so I had to have a look to see why ? there has to be a fix for it.I am a BMW panel tech and the BIG thing that BMW is good with is no noise in the car . The nuisance noise that occurs in these pillars is related to power train, wind, tire, and road noise. Over the years, various solutions have been used to minimize the energy level of noise that flows from these sources to these pillars. A current approach is to block the path of noise with heat reactive, expandable sealing materials mounted to support plates to create a"baffle". Baffles are strategically located within the body structure in a pattern that helps to eliminate propagation of noise into the vehicle passenger compartment.The good and bad news is to save money ford don't put any acoustic baffle or sound pads in but to stop the noise but we can.The big part that makes all the noise in the BA is that the boot floor is like a dum , The nuisance noise come's from the diff into the diff bush then into the body. If you have a look under where the diff bush is there is a metal brace going to a nice matel box, and in the box is air NO EXPANDABLE ACOUSTIC BAFFLE ..... thanks ford .So in the next week I will be looking more into it and filling the air with expandable sealing foam and adding some sound pads to the boot floor..

Probably do the spare wheel well and boot also. Link to comment Share on other sites More sharing options...

Guest STEVE_BAXR Guests Posted 16/08/09 01:48 AM Share Posted 16/08/09 01:48 AM OK I have the new test diff bush from Fulcrum, I have some photo's just to show how easy it was to put in MY WAY in under 20min .photo's show the old bush coming out and the new bush going in................ and the tools to do the job. The jack in the photo is just to hold the diff up to make it easy to put the bolt back in.Next is to take it for a drive to see if the NVH entering the cabin are not there or they are lower ..
