alaskanzx5 Posted March 4, 2014 Report Share Posted March 4, 2014 Consider using expanding foam in gaps? I did it in the hatch door of my other focus and it made a good difference as far as vibrations him flex go. If the goal is to reduce flex start with adding some where you have lots if flex them looking for more rattles it flex to fix. Once you think you have most of that taking care of work on using the foam passing stuff to block airborne Boise. Do it all in steps to get the result you want.

emperorjj1 Posted March 4, 2014 Report Share Posted March 4, 2014 just remember that expanding foam by itself doesn't actually do anything to filter or block noise its only useful as a physical barrier preventing something from moving... it can be very effective in certain situations Quote J.

P4killer_ Posted March 4, 2014 Author Report Share Posted March 4, 2014 Yea I used foam in my first trunk and it worked like crazy.. this trunk rather flat though with not many if any deep holes. More like a flat piece of flimsy metal. When you tap on iy with your hand you can hear just how flimsy it is. So there isnt really anything to fill with foam on the trunk lid. And i would like to avoid foam in the cabin asap.

alaskanzx5 Posted March 5, 2014 Report Share Posted March 5, 2014 Yeah my hatch door on my last car had a huge open area between the inner and outer metal filling that area helped a lot but I think most of that was sure to all the added weight.
