  1. My '99 (now sold and replaced my an '04 C4S Cab) had a problem. 5 months out of warranty, a 1" section of the plastic window came apart from the canvas. DSM would not cover a penny of it.

    Bought the window, had it put in by dealer. Window is about $700, labor is more. Problem is, half the time the zipper breaks. Mine did. When it does, it REQUIRES a new canvas top.

    Whole thing was about $3500+ for labor, window and top.

    I'd look into some aftermarket places to try this in your area before I'd spend the money on a high-price-for-labor Porsche dealer.

    Best of luck.

  2. FIXED!

    I had enough of this noise. Was beginning to wonder what the hell would cause so much squealing. Last weekend after washing and drying the car, I opened the top slightly until the boot cover moved back, and I checked the seals along the back edge, which I had 'gummi'd' already.

    Then I closed it up tight and cleaned the rear plastic window. As I was buffing the inside of the plastic window, down in the lower corner, driver's side, I created the SQUEAK on my own!!!!!

    I reopened the boot cover, and applied gummi to the bottom edge of the seal along the back of the cab top - but NOT all the way across - it was just in that one corner (I did the other corner too).

    Today, temp is above 60, sun is shining, and my cab is noise free.

  3. My '99 has been a relatively silent car for a number of good years, but last summer I noticed a noise sounding like rubber on rubber from the rear boot - the cover just ahead of the engine lid.

    I've used some gummi on the seal.

    The problem is only evident above 60 degrees and after sitting in the sun. Almost sounds like the old days of rubber motor mounts, or dead shocks - but it's not that bad. It's slight enough to sound like light creaking when I pull out of my office or over a speed bump, but not too bad once I'm on the move. And if the temp is low, or a cloudy day, nothing.

    I've checked most of the major issues, and it's odd since it started at about year five of the car's life. I've even adjusted the little pegs up under the boot cover (open it and you'll see them there) but no luck.

    And yes, I know cabs are prone to this - but with five years of relatively noise free life, I know I can get it back to that.

    Anyone have specific tips on where to apply the gummi or what else to look for?

    Thanks!

  4. After weeks of an annoying squeak, I took some time this past weekend to go deeper into the cab to find the problem. Thanks Loren for the documents. I did not have to remove the rear trim. I took out the windstop catch and found the felt was smashed to nothing, and replaced it with same. No change.

    I then noticed the small wings of canvas that fold up and down on each side of the top were separate pieces, plastic, with canvas over them. On the driver's side, I can move the piece when the top is closed or half open. When I move it, I get the squeak. So I peak down inside the cavity to see a small white nylon bushing of sorts, on a metal rod, with a spring. A spray of teflon rids me of the problem.

    For two days, at least. :(

    So now I'm puzzled. I know that is the spot, but I am uncertain if I should consider gummi or some other grease, or try to work with a spray/liquid product further.

    Any thoughts/comments?

    Thanks!

  5. As I delve further into this, and try to isolate the problem on my '99 C2 Cab, I find the driver's side rear window area and panel containing the speaker are the area from which this noise originates.

    Driving down the road it sounds like rubber against rubber. I dropped the seat back to see if that changed anything - nothing changed. I reached around and pressed on the back carpet against the firewall and it lessened a bit but not 100%. I also tried pressing on the side interior panel (speakers, windstop hold) and that seems to be the general fix.

    There's a lot of space in that general area looking down from the convertible top for the mechanism. Not sure if I should remove the side panel (what is best way) and install some felt or other sound deadeners (and risk the all to frequent worsening of the problem), or try another fix.

    Does not seem to be a window seal problem, though I'd not rule anything out yet. Definitely not dried out seals. They look and function just fine. And dropping the window a bit does not solve the problem.

    Thoughts?

    Thanks.

    :huh:
