The Doors on my IROC sound somewhat hollow, like I can hear an echo resonating through them, almost flimsy. My old RS however had very solid doors, they sounded like a seal was being made when I closed the door.

Does anyone else have this problem and if so, do you know if some dynomat or something will alleviate the problem ? Its not a major issue, however It is my intent to have these same doors Scissored (lamborghini'd, and your opinions on the matter are valid only to you as they are unimportant in this particular matter) and I don't want the doors sounding like they are about to fall apart. Any ideas ?

 

There's a lot inside the doors that get loose and rattley, but once you take it apart you'll see that there are several pieces that are "hooked" in one side and riveted in the other. Both methods of which tend to work loose after this much time.

My fix was to drill out the rivets, bend the tab back in so it's tight, then re-rivet it back in and dab a little silicone over the movable parts to absorb any future vibrations.

The sound deadener isn't really needed just to get that solid feel, but only helps.

The other major culprit is going to be the door handles. The springs that keep them from rattling tend to fatigue, or the tabs that hold them in break and allow the handle to wiggle around freely.

 

Does your door latch (the moveable part in the door) still have the plastic coating on it? If the plastic is removed or worn away the door will give a tin can sound as it hits the metal strike pin.

 

No it doesnt have the coating anymore, know how or where I can replace this ?

 

No. We might try ANDYZ28, He knows all about doors... I believe that it is really a plastic cover not a coating. I removed one on my junkyard door ( In an effort to remove binding) and now It makes the hollow sound lilke the old 55 chev used to.

At most hardware stores, there's a huge roll of plastic. I took this and used a little tape. It really made a difference.
