Rattle in the trunk

Rattle in the trunk - FIXED Since new, I have been getting rattles from the rear hatch area. It occurs on sharp bumps on the road. Finally I got the rubber mallet and started tapping around the trunk and the hatch. Nothing on the hatch. There it was right in the middle of the trunk on the floor where there is a bump. When I tapped that area, metal shields underneath the trunk just above the mufllers started squeaking with each tap. The sound varies from a click, similar to a wire hitting to a plastic/metal object to squeaking plastic, metal rattling sound transmitting into the car. Has anyone encountered it and been able to fix it without a major surgery? Cheers.

Trunk Clunk? I don't even want to fathom the number of articles, threads, and posts made about this subject... Scroll to the bottom of this page and click on those similar topics to see if what you have is the same problem.

Blue Eye: I had the same kind of noise, but after 3 months of searching, I finally located the noise is from the curtain hits the side of the aluminum cover in the trunk. always have small "****,****" noise. I removed the curtian in the hatch, drive the car and the noise is gone, even I go on uneven pavement road with speed small speed bump. Please try this and see if the noise is gone away! I hope this helps!

If it's the higher part of the rear trunk (over the engine) I had the same problem (clicky squeaky rattle sound) and cured it by levering up the carpet and jamming some foam rubber in there. If it's the lower part you'll probably have to do the same. Try taking the covers off either side (as if you were changing rear bulbs) and see if you can lift the carpet, then jam some foam rubber under there. Good luck!

vdeng, I had already removed the curtain...

blueyes, yes that is the exact place I am getting the squeaks from, the high part. How did you pry out the carpet, If I use a plastic pry bar from the edges will it come out and then it can be pushed back in?

Yeah, in general it sucks. I've owned two Porsches now, a 986 Boxster and my CS. With the Boxster , the rattles were bad enough that I almost sold it. With the CS, there's something from the rear that has been driving me up the wall and I've spent over $500 of my own money to try and fix it because the dealers are clueless and/or just don't care. I know from past experience if I brought it up with PCNA they'd just call it "normal" and would explicitly refuse to authorize any further warranty attempts to fix it. Even in this economy PCNA really just doesn't care about annoyances once they've made the sale. If your car dies, they are great about stepping up, but things like rattles are things they care nothing about, for better or worse.

Is it the same as the "Trunk Clunk" ? http://www.planet-9.com/cayman-boxster-complaints/17868-trunk-clunk-official-porsche-fix.html

If the sound or the rattle seems to be coming from the right rear speaker area, sounds like platic rattle or wire rattle or or very light weight things rattling over bumps..... I fixed my gremlins by removing the right hatch strut. The problem is 100% gone. I intitally got the strut replaced. The new strut did not help. When I disconnected one side of the strut laid it in the channel with some paper towel not to scratch, drove around, the noise dissapeared. I later sprayed the right hatch hinge with silicon spray. It helped 90% but the noise came back in a few days. Now I am driving the car without the right strut. Life is good . Note that the hatch with the left strut only will not stay up on its own. This does not bother me. When I need the hatch to stay up, I stick a broom handle to keep it up. Note that this rattle has nothing to do with the trunk clunk. Good luck.

Thanks, blue_eyes, I'll give that a try.

Got my rattling fixed yesterday Have taken my porsche to the service center 3-4 times this year to try to find a rattling which has grown worse over the last months. First the Porsche main importer to Sweden said this rattling would not be covered on warranty but this was changed after I talked to the manager there. This time the service guy moved the passager seat all the way front and squeezed himself in behind the seat to be able to easier locate where the noice was coming from. Sitting like that we went for a test drive. The noice was coming some where around the rear right speaker. When i picked up the car they said they had removed panels around that area and fixed some issues with some screws that might have vibrated against metall. Also they put silicon around the rear speaker cover. Finally the noice is come and I can just enjoy the sweet sound of the engine.

Maybe there is a gang of rogue babies going around, placing rattles in certain hatch areas? Maybe a bunch of outlaw rattlesnakes? Anytime I can be of assistance......

Re: Got my rattling fixed yesterday Thanks, I'll give that a try!

Thanks to all of you for the tips to (1) remove the curtain and (2) check/insulate the rear speaker. I will try both. My problems appear only during DEs. When I come in from my cool down lap, I always drive back to the pits with major squeaks. Maybe the specs are so tight that just a few millimeters expansion here and there from heat causes minor rubbing.

They do a great job, only took one call and its a lot easier to drive not getting bitten every time I step on the loud pedal :hilarious: The rear speaker location is close to where I had one of my rattles. I had one buzzing rattle in my driver side A-Pillar and another in the "C?" Pillar/Hatch plastic trim. Tech assumed I was coming in for the clunk or the center tail light rattling, but was neither in my case. He did mention those were the ones they fix most frequently on our cars. Ended up being metal brackets that were not tight enough used to hold those trim pieces in place.

Re: Got my rattling fixed yesterday Finally resolved the rattle, that is after 35,000 clicks. Happy, happy, happy Initially I thought it was from the right hatch strut, well got that replaced. It did not help. Sprayed the hatch hinges, helped a little but came back. Removed the right strut, it made a big difference towards better but it was still there. One day I realized when it rained or was wet, there was no rattle what so ever. And after 3 years of ownership I realized what it could be, the right hatch bumper, one that is halfway up on the hatch. I had read some threads here about that bumper, but never thought that could have been the cause. What I did was to apply a little red lipstick on the side of the bumper. The side that would touch the side of the trunk lip, not the bottom of the bumper. The bottom of the bumper is simply moving up and down and resting on the trunk lip. However the side touching the side of the trunk lip (the section covered with a clear protective film, was playing the violin every time the car moved up and down on a road imperfection.). After the lipstick treatment closed the hatch, pushed on the closed hatch just over where the rubber bumper would be. Opened the hatch and realized that the side of the bumper is actually in contact with the clear protective film. With a 220 sandpaper and a small piece of wooden block, supporting the sandpaper, removed about 1/16" of the rubber from the side. Re did the lipstick test and no more. Took the car for a lengthy drive with the struts in place, NO MORE NOISE. Another good test is to apply liberally silicon grease the side of the bumper (spark plug boot grease) and take it for a ride. If the noise is gone you have the same issue. Good luck. I will now put the privacy screen back on as well.

Re: Rattle in the trunk - FIXED, SOLVED, FOUND The passenger side trunk lid support strut is the problem. This rattle was driving me NUTS. I've been eliminating possibilities one at a time and decided to remove the right side strut. PROBLEM GONE. And the trunk lid WILL STAY OPEN with only one strut, as long as you push the lid all the way up (almost 90 degrees). Eventually I will look around and see if someone makes an aftermarket strut that does not produce this noise. In the meantime, I will enjoy my now rattle-free Cayman S.

Re: Rattle in the trunk - FIXED, SOLVED, FOUND I went to the dealer and bought a replacement strut only to find that the new one also rattled. The guy at the parts department was very helpful and did a little digging. He found that there is AN UPDATED PART NUMBER for the strut. I got the new strut and it is RATTLE FREE. The part number is 987.512.551.06 and cost about $50.

Re: Rattle in the trunk - FIXED, SOLVED, FOUND Thanks to posts on this thread, I found my rattle as the passenger side strut. FOUND A CHEAP REPLACEMENT THAT WORKS WITHOUT RATTLES. From Advance Auto, brand is StrongArm, part number 4287, about $23. It is slightly shorter and the barrel is wider than original, but it does not constrict the function, works perfect, and nothing hits. And best of all, RATTLE FREE!

A few pictures would have helped ...
