my lude is 95 si, and its pretty old...
a lot of my plastic parts inside are making rattling noises
such as the door part, front speakers, ceiling....
is there a way to get the rattling noise out? thx..

 

i took my entire interior out except for the dash and sound deadened all of the metal surfaces, this helped out a alot to keep the exhaust noise out, so the car didnt vibrate and rattle as much inside. There is a sound deadener called fat mat that works really well and it isnt as expensive as dynomat.
