Thats it!.. after a year.. I have finally gave up ignoring my rattling.. its sooooo terrible... drive somewhere and all u hear is the whole entire back end of the car RATTLING!@!

I cannot figure out what is the problem!..... inside my trunk I have a plastic lining... I've taken that wholeee thing off.. still rattles....

its like between the outside of the car and the inside ... broken PIECES of PLastic is flying alll around in there...

WHen i have my hatch up.. theres basically no rattling... only once the trunk is down... (but i think this is because most of the energy is escaping out and not rebounding off the walls)

HELP! and i don't think i'm willing to put Dynamat.. irelaly don't think thats going to help

Try small amounts at a time of spray expanding foam. Use it in the crevices and voids where you think the noise may be coming from. without damping material it's the only solution I can think of.

Used to have a 94 Probe. Theres no way arround it, due to an extreme lack of deadening (namely none at all) behind the body panels; rattling will happen.

Stopping the rattle is a rather extensive process, so be sure you have some time, some money, and a ton of mechanical aptitude on hand.

You will need to remove- ALL of your interior trim panels- save for the dash.

Most panels are held in place mainly by small push clips.

Once removed- use regular automotive grade undercoating and spray the back of all the panels pretty generously. Be sure and mask off any area's that could easily be victim of overspray. I have found that 3M Pro grade undercoat works best based on several different application tests that I have done.

Once dry- this will add the needed extra wieght to each panel to keep them from resonating.

Next - Using either dynomat or a similar product, line the entire rear portion of the car behind the panels- hatch and tire well included. Carpet padding works exceptionally well, and even adds a little more dampening due to its thicker padding; if you can stand to apply it with spray adhesive.

Once this is done, re-assemble the interior pieces.

Now, the entire rear bumper surround- remove it.

Much of the cars natural resonance occurs between the top of the bumper surround and the car itself. This is a molded fiberglass/plastic piece- it does not weigh that much.

Once removed- same procedure- undercoat the inside of the bumper cover very well. Several heavy coats may be necessary.

Next- purchase some foam weatherstriping and line the top of the surround completely. Allow at least 1.5" from the front side of the cover to make sure that the weather strip does not show when the panel is put back into place.

Put the bumper cover back into place- make sure all the bolts securing it to the car are snug.

Last step- Undercoating again. This time- the whole underportion of the rear of the car body on the outside. Tire well, etc.

This is quite an involved process, one which I have had the "luxury" of doing to 3 Probes.

All were whisper quiet afterwards however, so the "luxury" did pay off.

Be sure you apply the foam weather strip to the back of your license plate also.

take it easy,
